Hey Amgoth Tharun Absut,

Yes, it is ofcourse possible. You need to keep some points in mind. Make a good analysis of your jee mains. Identify your strengths and weaknesses. Solve atleast two practice papers of jee advanced every day. Analyze your mocks thoroughly. Keep working on the topics that are troubling you. Keep your formulas at your tips. Contact your mentors for versatile set of questions. Do not be in a hurry to attempt the paper, keep it slow but accurate.

Good Luck.
