MATHEMATICS:

This week, we will go through Binomial theorem for a positive integral index and properties of binomial coefficients. This chapter is again a very simple one and should not take much time. You can straight away jump to Section II of Eduwiser's Algebra by Prof. K. C. Sinha. The "Summary of Results" will help you revise all the theory portion of the chapter. You need to go through all "Worked Out Examples" including the "Prove that" ones because even these "Prove that" questions can be changed a little to frame any "New pattern question". Also solve all the exercise questions in this chapter from the same book.

Once you are done with this book, start practicing questions from Eduwiser Publishing Group's Mathematics for AIEEE by Prof. K. C. Sinha. Once again time your efforts here to build speed. Also solve "Questions Asked in Competitions" from the same book. In JEE Main, quite a few questions are expected to be from this book. Students, who are in Class XI right now and following my series of articles on JEE Prep, will have a chance to confirm this in May 2013.

One thing to note in this chapter is that even here, you can apply the same trick as the one we used in Sequence and Series chapter last week. Whenever we are asked a question where we have to calculate the sum to 'n' terms of an expression and the answer is also in terms of 'n', we can always put n = 1 or n = 2 and calculate the sum. Then, we can put the same value of n in the answers and see which answer gives the correct result. This technique will even work when the answers are independent of n.

It is also important now to start revising. So after completing the above chapter, you need to pull out Previous years' IIT-JEE questions and solve last 10 years' questions from the chapter Coordinates and Straight Lines.

Binomial theorem will take about sixteen hours of your time while revising Coordinates and Straight Lines will take about six more hours of time. So, a total of twenty-two hours for your Mathematics this week.

CHEMISTRY:

In Physical Chemistry, complete the following topics from Chemical kinetics: Rates of chemical reactions; Order of reactions; Rate constant; First order reactions; Temperature dependence of rate constant (Arrhenius equation).

First go through the theory and solved examples from Dr. A. K. Ghosh's Physical Chemistry book or your NCERT book. Then, you can go ahead with Dr. P. Bahadur's Numerical Chemistry and Dr. R. C. Mukherjee's Physical Chemistry. For the former, just solve the worked out examples but for the latter, solve the worked out examples as well as the exercise questions. This chapter will take you about nine hours to complete.

In Organic Chemistry, finish the following topics from Haloarenes: nucleophilic aromatic substitution in haloarenes and substituted haloarenes (excluding Benzyne mechanism and Cine substitution).

This portion should be covered from your coaching classes notes or from Prof. S. Lal's Organic Chemistry. You can also refer your NCERT book for the same. For Haloarenes, Organic Chemistry by Finar is good. If you can get hold of that book (borrow it from your school's or Coaching Classes' library), great but if you can't, you can go through Morrison and Boyd. You can allot about six hours to Organic Chemistry this week.

In Inorganic Chemistry this week, you should complete 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); Cyanide process (silver and gold). Cover these topics from your NCERT books and/or from your Coaching Classes notes. O. P. Agrawal's book can also help you if you do not have any Coaching Classes notes. Inorganic Chemistry will take seven hours this week.

PHYSICS:

In Physics, complete Systems of particles; Centre of mass and its motion; Impulse; Elastic and inelastic collisions from Dr. H. C. Verma's Concepts of Physics – Vol. 1 book. The last few questions of this chapter in the book are a little tough. So, if you are unable to solve any question, leave it for the time-being and attempt it next week. If you can't solve it the next week too, ask your teachers for the solution.

Another chapter - Hooke's law, Young's modulus is pretty easy but important. You can again refer to Dr. H. C. Verma's book. Allot twenty-six hours to Physics this week. Just in case you get some time, start solving new pattern questions from your Coaching Classes material.

Until next week, all the best!*(The author, Abhishek Chandra is the Founder of Eduwiser Publishing Group (www.eduwiser.in).
