Hi Aspirant, As you are interest in coding and programming you can go for CSE or IT , These two branches to can get good opportunities. Go for Jee mains and Jee advance, they 75% for general and OBC category and 65% for SC and ST category. you can go for study NITs,IITs,GFIT's and IIT's.

You can go for engineering in Computer Science. You have scored 80% in 12th in PCM, which makes you eligible for most engineering competitive exams. If you didn't write JEE Main this year (assuming you passed your 12th standard in 2019), you can wait a year and write it in 2020. There are other entrance exams as well like COMEDK, WBJEE, BITSAT, UPSEEE, SRMJEE, MU-OET, MHT-CET etc that you can write to get admission into engineering colleges.

If you don't want to pursue engineering, you can go for a BSc in Computer Science. You can apply to BHU, Madras University, Christ University, Presidency University for the same.

Alternatively, you can opt for a BCA course where you'll learn Computer Application. BHU, Jamia Millia Islamia, Christ University, Presidency University, Guru Gobind Singh Indraprastha University are some good colleges for the same.

Hope this helps. Good luck.
