Hello student

Yes, its completely normal to have a gap year after your class 12th. Many students take a gap year in order to prepare for entrance examination. You can apply for courses normally just like anyone else. However some college demands an affidavit for the gap year which is not compulsory in all colleges. You can talk about this with the college administration.

You can pursue BSc. CS from the following colleges-

Loyola College, Chennai

Fergguson College, Pune

St. Xavier's College , Mumbai

Atma Ram Sanatan Dharam College, Delhi

Thank!
