IIT Mathematics: Why it is important and which book is better?

IIT Mathematics books are important for I.S.I. preparation because they give a comprehensive problem collection on high school mathematics. I.S.I. entrance preparation has two layers.

Layer 1- High School Mathematics - Calculus, Trigonometry, Analytical Geometry, Algebra
Layer 2- Olympiad Mathematics - Plane Geometry, Combinatorics, Number Theory, Inequalities, Polynomials, Functional Equations

For high school mathematics portion, IIT Mathematics books are useful. Ofcourse you will need typical books like Maron for Calculus, Loney for Trigonometry and analytical geometry, Hall and Knight or Bernard Child for Higher Algebra, but to enhance problem solving ability you must have an IIT book as your companion.

There several such books available. Some of the most renowned are:

• M.L. Khanna,
• Tata Mcgraw Hill (TMH)
• Arihant
• Pearson
• Dinesh
• MTG

Each book has it's upside and downside but I have found that M.L. Khanna and TMH are the two most important books that serve our purpose. I will give M.L. Khanna some more points because it has a good mix of easier and difficult problems. It allows you to build your skill. On the other hand TMH is good for the already skilled one.

The bottom line is get M.L. Khanna IIT Math as a problem book. If you can finish it, you may move over to TMH.
