JEE 2013 Preparation – Week 9

Following is the plan for this week :

MATHEMATICS :

This week, you can start with the exercises of the chapter on Matrices from Eduwiser’s Algebra by Prof. K. C. Sinha. For the subjective questions, solve all questions except “Prove that” ones. For the “Prove that” questions, all you need to do is to have a look at the results that have to be proved. If the results have a general expression (e.g. in the form of a formula), try memorizing it because that might help you solve other questions more quickly. Needless to mention, solve all the new pattern questions from the book. This should take about eight hours of your time.

Also try to solve new pattern questions from your Coaching Classes material. You do not need to sleep over any of the subjective problems from this material. Earmark four hours for this.

After completing the above, you can finish off a very small chapter – Logarithms and their Properties. This chapter is there in Eduwiser’s Trigonometry. The chapter is very simple but important because of its applications in other chapters. For the theory portion, you can also directly refer Eduwiser’s Mathematics for AIEEE by Prof. K. C. Sinha. The theory in this book is very concise and takes very little time. You should also solve questions on Logarithms from the same book. Completing this should hardly take six hours.

CHEMISTRY :

In Physical Chemistry, we will cover the following topics of Solutions:  Raoult’s law; Molecular weight determination from lowering of vapour pressure, elevation of boiling point and depression of freezing point.

For the above topics, I would suggest you first go through Dr. Ashish Ghosh’s Physical Chemistry from Good Books to clear your basic concepts and then solve “Worked Out Examples” from Dr. P. Bahadur’s Numerical Chemistry from G. R. Bathla. Skip the exercise of Dr. P. Bahadur’s book. Instead, solve questions from Dr. R. C. Mukherjee’s Physical Chemistry. While you are solving questions from Dr. R. C. Mukherjee’s book, you can also practice new pattern questions from your Coaching Classes material. This should take about eight hours of your time.

Finish off the following topics from Surface chemistry:  Elementary concepts of adsorption (excluding adsorption isotherms); Colloids: types, methods of preparation and general properties; Elementary ideas of emulsions, surfactants and micelles (only definitions and examples). This chapter is again very simple and short. You can refer your Coaching Classes notes for the same along with Dr. P. Bahadur’s or Dr. A. K. Ghosh’s book. You should be able to wrap this chapter up in about four hours of time.

For Organic Chemistry, cover the following topics of Aldehydes and Ketones: oxidation, reduction, oxime and hydrazone formation; aldol condensation, Perkin reaction; Cannizzaro reaction; haloform reaction and nucleophilic addition reactions (Grignard addition).

Study the above from your Coaching Classes course material or Prof. S. Lal’s Organic Chemistry from Good Books publishers. Organic Chemistry by Morrison and Boyd has to be referred to give you an idea of how reactions occur. Memorize all the reactions. You should be able to count the number of reactions of each chapter. Also go through the book on Reaction Mechanism by Sanyal. All this should take about eight hours.

In Inorganic Chemistry this week, you can cover Carbon: oxides and oxyacid (carbonic acid); Silicon: silicones, silicates and silicon carbide; Nitrogen: oxides, oxyacids and ammonia; Phosphorus: oxides, oxyacids (phosphorus acid, phosphoric acid) and phosphine; Oxygen: ozone and hydrogen peroxide; from your Coaching Classes course material or NCERT books. This should take eight hours of your time.

PHYSICS :

I hope you must have covered the topics I suggested you to complete last week. Take about seven more hours of time to finish them off if you have not been able to.

Then, you should move onto Electromagnetic induction: Faraday’s law, Lenz’s law; Self and mutual inductance; RC, LR and LC circuits with D.C. and A.C. sources. The chapter is short and should not take much time. Refer the same book – Dr. H C. Verma’s Concepts of Physics – Vol. 2 for the above topics. Get rid of any doubts you have at once from any source possible. This chapter will take about six hours.

The balance eleven hours have to be used to solve new pattern questions and questions from last ten years’ IIT-JEE from the chapters Current Electricity, Magnetism and Electromagnetic Induction. This will give you an idea of the level questions you can expect in JEE – Mains and Advanced. At this point, it will also help to refer to MCQ by Prof. Deb Mukherji from Bharti Bhawan publishers. The book has a superb collection of questions and will help you think like an IITian!

Until next week, all the best !

JEE 2013 Preparation – Week 8

Following is the plan for this week :

MATHEMATICS :

Since we have already finished theory and Worked Out Examples of the chapter Quadratic Equations, we will finish the exercises of the same chapter from the book Eduwiser’s Algebra by Prof. K. C. Sinha. (The Prof. K. C. Sinha series by Eduwiser Publishing Group is ow available on www.flipkart.com). You need to solve each question. Try not asking for help until the last day of this week. However, if you are unable to solve any question by the end of this week, you should ask for help at your school/coaching classes.

Once you are done with the exercises of the book, try solving only new pattern questions from any Coaching Classes material. You do not need to go through subjective questions from sources other than your textbook.

Also solve questions of the same chapter from Eduwiser’s Mathematics for AIEEE by taking timed tests as you did with the chapter on Complex Numbers. This should take about fifteen hours of your time in all.

After you are done with Quadratic Equations, allocate time for the chapter on Matrices from the same book. Be thorough with the theory portion because one that is clear, solving problems will be very easy. Also try to solve Worked Out Examples from the same book. This should take about six hours of your time.

CHEMISTRY :

In Physical Chemistry, we will cover the following topics of Solid State : Classification of solids, crystalline state, seven crystal systems (cell parameters a, b, c, α, β, γ), close packed structure of solids (cubic), packing in fcc, bcc and hcp lattices; Nearest neighbours, ionic radii, simple ionic compounds, point defects.

Do not bother too much about this chapter if you are finding it very difficult. As a general feedback that I have received from students about this chapter, it is a boring one and students normally leave this chapter. However, it will not harm to go through this chapter once so that, in case a simple question is asked from this chapter, you do not get stumped.

You could refer your Coaching Classes notes as well as any foreign author book for this purpose. Clarify your doubts as soon as you have them.

Try to work out new pattern questions from your Coaching Classes material as well as questions that have been asked in previous years’ IIT-JEE and AIEEE. All this should consume about ten hours of your time.

For Organic Chemistry, cover the following topics of Phenols : Acidity, electrophilic substitution reactions (halogenation, nitration and sulphonation); Reimer-Tieman reaction, Kolbe reaction.

After you are done with this, you can cover characteristic reactions of the following :  Alkyl halides: rearrangement reactions of alkyl carbocation, Grignard reactions,  nucleophilic substitution reactions;  Alcohols: esterification, dehydration and oxidation, reaction with sodium, phosphorus halides, ZnCl2/concentrated HCl, conversion of alcohols into aldehydes and ketones; Ethers : Preparation by Williamson’s  Synthesis.

Study the above from your Coaching Classes course material or Prof. S. Lal’s Organic Chemistry from Good Books publishers. You should again refer Organic Chemistry by Morrison and Boyd for any concept that you do not understand. Remember one thing with the above topics : you should memorize all the reactions and should be able to close your notes/books and still be able to recall all the reactions. You could try revising the reactions while traveling or while in your school whenever you get some free time.

Organic Chemistry will take eleven hours of your time.

In Inorganic Chemistry this week, you can cover Principles of qualitative analysis: Groups I to V (only Ag⁺, Hg²⁺, Cu²⁺, Pb²⁺, Bi³⁺, Fe³⁺, Cr³⁺, Al³⁺, Ca²⁺, Ba²⁺, Zn²⁺, Mn²⁺ and Mg²⁺); Nitrate, halides (excluding fluoride), sulphate and sulphide from your Coaching Classes course material or NCERT books. This should take another eight hours of your time.

PHYSICS :

In Physics, you must have already started the chapter on Magnetic Field. You should finish Biot-Savart’s law and Ampere’s law; Magnetic field near a current-carrying straight wire, along the axis of a circular coil and inside a long straight solenoid; Force on a moving charge and on a current-carrying wire in a uniform magnetic field from Dr. H. C. Verma’s Concepts of Physics – Vol. 2.

Also finish Magnetic moment of a current loop; Effect of a uniform magnetic field on a current loop; Moving coil galvanometer, voltmeter, ammeter and their conversions from the same book.

Pay attention to the theory of the above topics because it can make or break things for you. Any doubt in the theory should be clarified at once without any delay and before solving questions. You will have to solve each question from the book.

You will also need to try out new pattern questions from your Coaching Classes material. If you are not able to solve any question, you can try it again next week by yourself. Physics will take about twenty hours of your time this week.

Until next week, all the best !

JEE 2013 Preparation – Week 7

Following is the plan for this week :

MATHEMATICS :

This week, we will cover one of the most important chapters on Algebra – Complex Numbers and a bit of Quadratic equations. Refer the book Eduwiser’s Algebra by Prof. K. C. Sinha for both the above chapters. Since you have already covered Complex Numbers in Class XI, move straight to Section II. Go through the “Summary of Results” thoroughly. If you find difficulty with any of the concepts in “Summary of Results”, refer Section I for explanations. Go through the “Worked Out Examples” except those “Prove that” ones that are more than a page long. Solve all the “Worked Out Examples” of New Pattern Questions.

Solve each of the subjective questions in exercise (there are just 20 of them). With the Straight Objective Type Questions, try to time your attempts (say 10 questions at one go). This will help build your speed. You will also find “Questions Asked in IIT-JEE” at the end of the book. Try to solve each question yourself independent of the time the questions take.

While going through Complex Numbers, try to build some analogy with Coordinate Geometry. This will make things easier when solving questions based on Argand Plane. Always make a figure before you start solving because it will give you a better understanding of the problem. This chapter should take you fifteen hours of time.

Once you are done with Complex Numbers, start with Section II of Quadratic Equations. Follow the same strategy as with Complex Numbers. By the end of this week, you should finish “Summary of Results” and “Worked Out Examples” of this chapter. Special attention and time should be given to the concept and problems on “Sign scheme”. This will consume seven hours of your time.

At any time during the week, you should find about four hours of time to solve questions of Coordinate Geometry and Straight Lines from the practice book -  Eduwiser’s Mathematics for AIEEE by Prof. K. C. Sinha. This book also has questions asked in various competitive examinations (like IIT-JEE, AIEEE, West Bengal JEE, Orissa JEE, Karnataka CET, Kerala CET, etc.) and one needs to solve these questions to better his/her chances of qualifying JEE Mains. Try to take timed tests of yours with the questions of this book. Many questions have been directly asked from this book in past competitive examinations.

 

CHEMISTRY :

For Physical Chemistry this week, we will keep it light with the following topics – Concept of atoms and molecules; Dalton’s atomic theory; Mole Concept; Chemical Formulae; Balanced Chemical Equations; Calculations based on mole concept involving common oxidation-reduction, neutralization and displacement reactions; Concentration in terms of mole fraction, molarity, molality and normality. The theory and Worked Out Examples of the above topics can be covered from Dr. A. K. Ghosh’s Physical Chemistry from Good Books publishers followed by Worked Out Examples only from Dr. P. Bahadur’s book. If you do not have Dr. A. K. Ghosh’s book, you can work out questions from Dr. R. C. Mukherjee’s book.

Try solving new pattern questions from your Coaching Classes course material. Physical Chemistry will take away ten hours of your time this week.

For Organic Chemistry, we will wrap up Reactions of Benzene – Structure and aromaticity; Electrophilic substitution reactions : halogenation, nitration, sulphonation, Friedel-Crafts alkylation and acylation; Effect of o-, m- and p-directing groups in monosubstituted benzenes. We will also have enough time to finish the following topics from Phenols – Acidity; Electrophylic substitution reactions (halogenation, nitration and sulphonation,); Riemer-Tieman reaction and Kolbe reaction. You could again use your Coaching Classes course material for the above or Prof. S. Lal’s Organic Chemistry from Good Books publishers. You should refer Organic Chemistry by Finar or Morrison and Boyd for any concept that you do not understand. There is another book - Solution to Morrison and Boyd. This book is very useful to have as it has solutions to questions that are there in Morrison and Boyd.

Organic Chemistry should take about ten hours of your time this week.   

In Inorganic Chemistry this week, you should finish Extractive Metallurgy – Chemical principles and reactions only (industrial details excluded); Carbon reduction method (iron and tin); Self-reduction method (copper and lead); Electrolytic reduction method (magnesium and aluminium) and Cyanide process (silver and gold) from your Coaching Classes course material or NCERT books. This should take another eight hours of your time.

PHYSICS :

This week, cover the topic Heating Effect of Current from the chapter Thermal and Chemical Effects of Electric Current from Dr. H. C. Verma’s Concepts of Physics – Vol. 2. You do not need to read through or solve questions from portions other than Heating Effect from the same chapter. This should hardly take four hours of your time.

Start the chapter on Magnetic Field from the same book. Give enough time for the theory portion because once you are clear with the theory part, solving any kind of question from this chapter will be a cake walk. You have to clear all your doubts in the theory of this chapter at once. Read through the “Worked Out Examples” instead of solving them. You need to solve each question of the exercise. If there is any question you cannot solve from the exercise, give it another try after we finish the chapter on Electromagnetic Induction in future. At this point of time, you need not worry about solving new pattern questions of this chapter from any source. This chapter will take about twelve hours of your time.

I do hope you are keeping pace with the schedule I am giving. Until next week, all the best !

JEE 2013 Preparation – Week 6

Following is the plan for this week :

MATHEMATICS :

From the same book – Eduwiser’s Vectors and 3-D Geometry by Prof. K. C. Sinha, work on chapters - Introduction to Three Dimensional Geometry, Angle Between Two Lines, Straight Lines and Plane before working on the Straight Objective Type Questions from Competition Section of Vectors portion. The strategy here will almost be the same as that for the Vectors section – go through the theory portion of all the chapters and the worked out examples. From the exercises, solve a couple of questions of each type. There is no need to solve each and every question from the exercises. What you should do while solving questions here, is trying to solve the same questions by Vector method as well. Almost every question in Three Dimensional Coordinate Geometry can be solved using Vector method and vice versa, so keep that in mind.

After you are done with the above, switch to the Competition Section of 3-D Geometry. Solve all the worked out examples, including the “Prove that” ones. However, from the exercise of Subjective Type Questions, you can skip “Prove that” questions. Also solve all the new pattern questions (including the Straight Objective Type Questions) from the same book.

Once you are done with the above, you should finish the Straight Objective Type Questions of Vectors section. Now, when you are solving questions here, try to solve it using 3-D Geometry method too. Very often, the solution in 3-D Geometry method will be a lot simpler and easier to work upon. This is majorly because 3-D Geometry has tremendous similarities with 2-D Coordinate Geometry that we have already worked on. You have to be thorough with Vectors and 3-D Geometry because these topics are very easy and the questions asked from these topics are fairly simple and scoring. I have come across numerous IIT aspirants who have ignored Vectors and 3-D Geometry and have regretted it later.

All the above should take about thirty hours of time.

CHEMISTRY :

This week’s target in Physical Chemistry will be Chemical Equilibrium. This chapter is one of the medium difficulty ones in Physical Chemistry and can help you score with slight effort. The topics that you should concentrate on under Chemical Equilibrium are – Law of mass action, Equilibrium constant, Le Chatelier’s Principle (effect of concentration, temperature and pressure); Significance of DG, DGo in Chemical Equilibrium, Solubility Product, common ion effect, pH and buffer solutions; Acids and bases (Bronsted and Lewis concepts); Hydrolysis of salts.

Cover these topics from Dr. P. Bahadur’s book as well as Dr. R. C. Mukherjee’s book. Solve only the worked out examples from Dr. Bahadur’s book whereas solve each question from the worked out examples and exercise of Dr. R. C. Mukherjee’s book. Also practice new pattern questions of the above topics from Coaching Classes Course material. All doubts from the above topics should be cleared at once with help from your teachers.

All of this should take not more than fifteen hours.

For Organic Chemistry, we will finish off Preparation, properties and reactions of alkenes and alkynes – Physical properties (boiling points, density, dipole moments), Acidity of alkynes; Acid catalyzed hydration of alkenes and alkynes (exclude stereochemistry of addition and elimination); Reactions of alkenes with KMnO4 and ozone; Reduction of alkenes and alkynes, Preparation by elimination reactions; Electrophilic addition reactions of alkenes with X2, HX, HOX and H2O (X = halogen); Addition reactions of alkynes and Metal acetylides, from your Coaching Classes course material/Organic Chemistry by Prof. S. Lal. You should also refer the book on Organic Chemistry by Morrison and Boyd in case you do not understand any of the topics mentioned above.

This should take five hours of your time.

In Inorganic Chemistry this week, you should finish Ores and minerals of iron, copper, tin, lead, magnesium, aluminium, zinc and silver from your Coaching Classes course material or NCERT books. This should take another five hours of your time.

PHYSICS :

In Physics, we will cover the chapter on Gauss’ Law and its application as well as the chapter on Capacitance from Dr. H. C. Verma’s Concepts of Physics – Vol. 2. Both the chapters are simple. In fact, the chapter on Capacitance is very similar to the chapter on Current Electricity. Try to draw parallels between the two chapters and you will notice that the same principles are used on solving questions from both the chapters.

Pay special attention to the chapter – Capacitance. The base has to be very strong and you should practice hard to make it so. Get your doubts from Gauss’ Law resolved at once but do not do this for Capacitance. Try solving the questions yourself. Keep in mind the steps you follow for different types of questions and stick to them.   

Also try solving new pattern questions from your Coaching Classes material. This week, Physics should take up about fifteen hours of your time.

(Some students have written back to me personally saying that they have not joined any Coaching Classes and hence do not have access to their material. In this case, you can either borrow it from your seniors who have already taken admission in some college, or from your friends. If neither works, you can enroll for the correspondence material from FIITJEE, Akash or Prof. K. C. Sinha Classes.)

Until next week, all the best !
