Hii Tharuni

As you are just 2 weeks away from appearing for one of the most important exams of your life . You can revise all the topics throughly and ask your teacher/mentor to clarify all your doubts and practice problems as many as you can . Go through previous mocks and analyse your mistakes in them and improve them . You can revise the topics you feel are really important as JEE point of view and study them .

Best of luck

Hope it helps

Thanks!!!
