Hello aspirant,
Hope you're doing well!
Along with all the documentation you're submitting in your college when taking admission, you need to have an affidavit which is basically a proof that you didn't take admission in any other college for the past 2 years.
You also need to write the reason for the same, which can be anything:personal reasons, education etc:.
Some of the coachings also provide you with the gap certificate if you ask them ( only for those who were enrolled in coachings)
