You can take one year gap provided that when you take admission in any college or university of India you are required to have obtained certificate of gap and will have submitted it in the college or university in which you are taking admission. The other thing is that for what reason you are taking one year gap. You must have a clear answer for taking gap. Like if you want to prepare for entrance examination such as NEET or JEE and want to have a good college with good placements scholarships and a brighter career, then you should take gap for making your future brighter. For applying for a gap certificate, you are need to contact a lawyer so that he can make this affidavit for you at reasonable charges.

Dear Student ,

Generally , after class 12 .. many students take a drop for preparing for engineering exams or some other entrance exams ... well, as per some colleges eligibility criteria , they can accept the admission of students upto two years from their 12th qualifying exam. But, remember .. the requirements may vary institute wise .. But , you can freely study distance course programs from any OPEN University like IGNOU  etc as there is no upper age criteria is mentioned .

It would be helpful for me to help you more if you could mention your choice of domain (like BA, B.tech etc) in your query.

Hope you understand !

Best wishes !!

Hello!

No there will be no problem for you to get admire in any of the college. It's your choice to whether drop one year or not. But every year the completion rises and cut offs do get higher every year. So before you drop out be sure about it. Anyways there is no problem.
