JEE 2013 Preparation – Week 10


Following is the plan for this week :


MATHEMATICS :

Start Permutations and Combinations from Eduwiser’s Algebra by Prof. K. C. Sinha. It will help to go through the Section I of this chapter first. Go through the theory and “Worked Out Examples” thoroughly. You do not need to solve each question from the exercise of Section I here.

Once you are done with it, start Section II. Go through the “Summary of Results” first. If you have any doubts understanding the results, refer Section I theory again but be thorough with the theory and concepts involved. Each book in the market has a different way of solving the same question. What I have noticed is that, in other books, the methods explained are not general and cannot be applied to most of the questions. That is why things become a little difficult and confusing in this chapter. But with the book I have suggested, you should be able to find general methods of solving different types of questions. Going through the “Worked Out Examples” will help you clarify and brush-up your concepts of the chapter and the methods you would have learned from the same book. You should then solve all the questions (including “Prove that” ones) from the book. Lay emphasis on new pattern questions. If you fail to solve any question, give it a try next week but in case you still are not able to solve the question next week, get help from your teachers.

Also try to solve new pattern questions from any source possible. You will also be able to get abundant questions from this chapter on the internet. Try solving them using the concepts you have learned from the book.

After you are done with Eduwiser’s Algebra, work out questions of the chapter from Eduwiser’s Mathematics for AIEEE. Here, you should again try to take timed tests of yours to build your speed. The entire Permutations and Combinations should eat up about twenty hours of your time.


CHEMISTRY :

In Physical Chemistry, we will cover the following topics of Nuclear chemistry:  Radioactivity: isotopes and isobars; Properties of α, β and γ rays; Kinetics of radioactive decay (decay series excluded), carbon dating; Stability of nuclei with respect to proton-neutron ratio; Brief discussion on fission and fusion reactions.

You just need to refer to “Worked Out Examples” from Dr. P. Bahadur’s Physical Chemistry and “Worked Out Examples” with exercise from Dr. R. C. Mukherjee’s Physical Chemistry. This chapter becomes very important because of two reasons. One, there is minimal risk with this chapter. If you have sincerely solved all the questions from the books suggested, chances are high that you will be able to solve the questions of JEE Mains and Advanced. You can test this by trying to solve questions asked in previous years’ IIT-JEE. Two, the same chapter appears in Modern Physics. With the same theory, you should be able to solve questions asked in Physics from the same chapter.

Also try solving questions from previous years’ IIT-JEE and new pattern questions from various sources. This chapter will take approximately ten hours of your time.

The target for Organic Chemistry will be to finish Carboxylic acids: Formation of esters, acid chlorides and amides, ester hydrolysis. Follow your Coaching Classes notes or Prof. S. Lal’s Organic Chemistry along with Morrison and Boyd for concepts that you do not understand. Try to justify each reaction of the chapter as you study.

Also solve questions that have been asked in previous years’ IIT-JEE and clarify your doubts as soon as possible. Organic Chemistry should consume about eight hours of your time.

In Inorganic Chemistry this week, you can cover Sulphur: hydrogen sulphide, oxides, sulphurous acid, sulphuric acid and sodium thiosulphate; Halogens: hydrohalic acids, oxides and oxyacids of chlorine, bleaching powder; Xenon fluorides from your Coaching Classes course material or NCERT books. At this time, you should also solve questions asked in previous years’ competitive examinations. This should take nine hours.


PHYSICS :

For Physics this week, we will get rid of the following topics from Thermal physics: Thermal expansion of solids, liquids and gases; Calorimetry, latent heat; Heat conduction in one dimension; Elementary concepts of convection and radiation; Newtons law of cooling; Ideal gas laws; Specific heats (Cv and Cp for monoatomic and diatomic gases); Isothermal and adiabatic processes, bulk modulus of gases; Equivalence of heat and work; First law of thermodynamics and its applications (only for ideal gases); Blackbody radiation: absorptive and emissive powers; Kirchhoffs law; Wiens displacement law, Stefans law.

Needless to mention, all this topics should be covered from Dr. H. C. Verma’s Concepts of Physics – Vol. 2. All the topics of Thermal Physics are high scoring, low risk topics. You have to be thorough with them. If you are thorough with them, there will be no question of JEE Mains and Advanced from these topics that you will not be able to solve. Special hint for the chapter on Heat Transfer from Dr. H. C. Verma’s book is to compare it to Current Electricity.

Try solving previous years’ questions from IIT-JEE, new pattern questions from Coaching Classes material and objective questions from Prof. Deb Mukherjee’s MCQ. Physics will take about twenty-three hours this week.

Until next week, all the best !

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: Faradays law, Lenzs 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-Savarts law and Amperes 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 !
