HI,

Probability, statistics, permutations and combinations, AP/GP, trigonometry, mensuration, circles, linear equations, relations and functions, 3 dimensional geometry, vectors, straight lines, integration, differentiation, application of differentiation, matrices, sets.

THESE TOPICS ARE FROM CLASS 11 AND 12. JUST LEARN BASIC TECHNIQUES OF SOLVING THE QUESTIONS AND BUILD UP CONCEPTS. OUT OF 30 QUESTIONS OF MATHS APPROX 10 TO 15 CAME.
