Hello.I am a student of class X.I want to pursue computer-science engineering at IIT,Bombay.Please give me some tips so that I can start my preparation for it.

Dear Student
During class 10 make sure you're clear with basic concepts. After you're done with that you can refer to some class 12^thtopics. Few class Class X are similar to tenth. So study those chapters in detail. Make sure to practise a lot of questions. Focus on NTSE and olympiads. It will be helpful for JEE
