if you study in AP state board, and take MPC group, then preparing for iit should more or less make you adequately prepared for board. but there are a few catches, for instance the board exams require 2-3 pages answers for questions that carry more weightage. having said all this, if you are currently studying in ap state board, then may god help you because you faced a lot of bandhs this year.
12th score whether cbse or state board. most students take serius in entrance than board. so allow them to concentrate on one thing. cbse or state board if they score 60% is enough .
