Certificate

Yes you definitely need a gap certificate when you go to take admission in any college.
You have to mention in that certificate about any other course or any other diploma you have done in that particular year.
Gap year is basucally kept for the record purpose of the student.

Yes, you can definitely study for your graduation and certificate course simultaneously. Many students do that even I did that. Just see to it that your certificate course does not overlap with your normal college timing as attendance in both the cases matters.
