The cut-off for screening has been around 40-45% which may change depending upon the toughness of the paper. Detailed statistics can be found at http://www.123iitjee.com/iitjee_stats.htm
.

The preparation for mains should automatically take care of preparation for screening. However, here are the recommendations for the objective questions since you asked:

Physics-H.C. Verma and MCQ (Bharti Bhavan)
Chemistry-Arihant
Mathematics-Arihant

Your job is to prepare and not to worry about the result. Fear will find no place if you think that way.

Sum of the coefficients in the expansion of $(x+y)^n$ ....

If the sum of the coefficients in the expansion of $(x+y)^n$ is 4096, then the greatest coefficient in the expansion is _ _ _ _ . Solution $C_0 + C_1 + C_2 + C_3 + ......................... + C_n =4096$ $\therefore 2^n = 4096 =2^{12}$ $\Rightarrow n = 12$ Greatest coefficient = ${}^{12}{C_6} = 924$
