Dear Rohan

Rohan definitely you can able to achieve your target. If accordingly you have done the preparation for it . Since now you are in class 11th then you should have to complete the full syllabus of the JEE mains as well the board too from the NCERT and RD Sharma too. Try to do the more no of mock test after the completion of every topics of PCM domain. And when you will class 12th first try to complete the whole syllabus asap and previous 10 years IIT-JEE paper. Follow the proper timings for your preparation as well strategies too.
Go through the syllabus of JEE mains properly and select those topics of Class 11th which has more weightage of marks and practice them well.

All the best
