Hey Deepak,

Taking a gap year after 12th grade is not a problem if you spend the time appropriately. Even if you are a gap student, colleges will accept your application if you meet their qualifying requirements as per my knowledge. Although, seek for the college's specifics so that you are informed of the procedures and needs. You may be asked to sign an affidavit explaining why you took a two-year break. As a result, maintain the documentation on hand.

Hope it helps

Regards.
