Since I have been through the most gruelling period of my life, I've got some tips to give you. I believe
that Self Study helps the most.....avoid tuitions.
Recommended Books:
PHYSICS:
Concepts of Physics 1 & 2 (H C Verma)
Problems in Physics (I E Irodov)
H C Verma book is enough for objective questions
CHEMISTRY:
Organic Chemistry (Morrison & Boyd)
Numericals (R
C Mukerjee)
Physical & Inorganic (IIT Chemistry by Aggarwal)
For Objective questions concentrate more on +2 books and R C Mukerjee
MATHS:
A Textbook of (Algebra, Calculus, Trigonometry, Co-ordinate Geometry,Vector, Probability)
K C Sinha (All Separate Books)
This is more that enough for any kind of entrance exam
So........keep the faith and keep studying. Success will be yours.
Best of Luck!
