You have to prepare for entrance examinations and feel forms of the following exams - Jee Mains, CET, COMEDK, BITSAT, etc. To get local colleges of your own state, cet will help you better and to get the best colleges in this country, other exams will surely help you. Andd work honestly force the CS course and don't think negative for now. If in case you need a backup plan, then maybe BSC in CS or something like that will be good for you.

Best wishes. Thank-you.
