Hello dear student,

Usually average students only crack JEE exams no one is extra ordinary but you have to really prepare well if you are very serious about going into a good engineering College or to your dream college.

Just make small goals, make a proper time table, try solving previous year question papers and after you study or you are done with one chapter on the concept then try to solve the questions related to that topic because that will give you a command on the questions.

I hope this helps.  Thank you
