Hey,

Yes, of course. You should give your best. With the right strategy and right guidance, you can easily get a good rank. Start with NCERT's, make sure that you go through them thoroughly. After this give online mocks/ attend some test series. Analyse your mock for 3-4 days. This way try to give a mock every week. If you will do this until the end. There will be high chances of your success.

All the best!
