which is the most imprtant as well as tht has the most weightage topics in physics and maths in iit entrance?

in maths it is calculus, whereas in physics it is kinematics,fluid mechanics

MATHS: CO-ORDINATE:- straight line, circle, locus. ALGEBRA:- complex no.,qudratic equation,probability,a.p.,g.p. CACULUS:-LIMIT,CONTINUTY,integration,application of calculus. Trigonometry all are important (carries near about -5marks each year) PHYSICS: mechanics,kinematics,vectors,gravitation,atomic physics, Electronics and electromagnetism. CHEMISTRY:- bonding, organic chemistry, metals.however tough questions are from physical part. ABOVE MENTIONED ARE THOSE PARTS WHICH CARRY MUCH WEIGHTAGE IN IIT-JEE. You can able to score more then 150 just preparing this nicely. And also give as much as mock tests possible,it will bring perfection to you. Best of luck Source

you read

only mechanics in physics u qualify in aieee but never done this u read carefully all topics.
