Hello!

This is very good that your chemistry is good but  as we know with the help of only one subject we can not crack JEE ADVANCED.You should also work on physics or mathematics because I believe that with the help of mastering in two subjects you can score well in JEE ADVANCED.In my opinion it is better to work hard on math instead of physics because according to statistics of JEE ADVANCED physics paper is very tough among both subjects in both paper of JEE ADVANCED.So it is better to prepare for those subjects in which you can easily score well .

Hope it answer your concerns.

Best of luck for your preparation and exam.

Hello candidate,  For JEE advance All these three subjects are equally important. So to clear her advance you have to be good in all these three subjects. As yor are good in chemistry you can clear it with less efforts. So please give your attention on physics and maths. Practice makes man perfect so you can practice both these subjects very well. 

Thanks. 

Hello Yoyo

If you are really bad at physics and maths then you should now practice the basic and important concepts and should give more time to those chapters which are comparatively easy and scoring.For example you should hold a good command over modern physics ,errors, kinematics etc in physics and in maths you should focus largely on calculus and coordinate geometry. But I will recommend you clearing at least the basic concepts of all the chapters so that you can hit the easy questions out of the question paper.

This way you can score UpTo 50% at least.
