Engineering Entrance Exam

Hello Abhishek,
If you are quite clear over your concepts then coaching's study materials will be enough for you to score some good marks in JEE Mains and Advanced, however, join any good and reputed test series to get the glimpse of examinations.
All the best!

I think that your scores do not depend on a coaching institution and so is your preparation. Every coaching is equal but Gravity Coaching Institute is the best.

Hello,
To appear for JEE Mains exam, the criteria is that you must be studying in class 12th with equivalent 75% and above.

Wait till the counseling date is announced. After that, you will know everything. Everything will be provided at the website.

You score should be a minimum of 200 this year.

Obviously, you will get as your rank will be around 1000-1500. If you belong to OBC/SC/ST then you will get CSE in the top 5 IITs. In case of general category, you will get CSE in IIT Roorkee or IIT BHU or IIT Guwahati. But from this year, this trend may change. Best of luck!

I think you should prepare for GATE exam.
