I want to read B.Tech in computer science. How should I prepare to get good marks?

Hi Priyanka Prepare for JEE. The most important thing to crack JEE is to go through previous year's JEE question papers which will give you an idea and variety of the questions will clear your misconceptions. I hope it will help you.

Hard work has no substitute. That's the only thing you can do. Stay focused and work sincerely.
