IIT

Mathematics:
NCERT Mathematics Part I and II is the prime book to initiate and later students can shift on to R. S. Agarwal and other practice materials. The important topics such as geometry and trigonometry has to be covered from Tata McGraw Hill as it has all the important questions expected in the JEE Main. Statistics can be covered from again NCERT and S. Hand as it carries the detailed formulae and usages of it mentioned briefly. Physics
The students shall initiate the preparation from the NCERT part I and Part II, in order to clear the basics and make a strong foundation for further detailed and analytical part. It is always advised to read the complete chapters and clear every concept perfectly before you initiating the problem solving. Later on the students can try out for the H. C. Verma Physics book which is the most important book for Class 11 and Class 12 students. Chemistry
As Chemistry is divided into Organic and Inorganic, Physical and Numerical, there has to be more than 2 or 3 books needed to cover it completely and thoroughly. For Physical Chemistry, students must refer the O. P. Tandon as it comprises all the basics of Physical Chemistry. P. Bahadur (G. R. Bathla & Sons) has all the major contents of Numerical Chemistry explained with problems and their solutions. For Inorganic Chemistry R. K. Gupta is said to be one of the best book to refer. Papers
Students should also prepare from various sample papers and practice papers available online and offline. These are created byPapers some of the very experienced professionals with years of experience who know the complete in and out of JEE and entrance.

Hello Anu,
As on today, National testing agency has only announced the tentative schedule for conducting JEE Advanced for entry into different IIT's. Presently even the all India ranking of JEE Mains has not been announced. Of course, even today there are some software prepared by different websites which will predict college or IIT for you based on your rank of last year but I would advise caution and patience. All these software make use of the past data and it is better to use the last year's data for guessing something as vital as admission into IIT. I feel by the beginning of April or May there will be enough software which will predict the rank in JEE Advanced or predict the college based on the rank in JEE Advanced. Best wishes to you.
