Hello Student,
If you have passed all the subjects then you are eligible for some of the competitive exams you wish to appear in your stream. But there are some entrance exams whose eligibility criteria for appearing is to score more than 50 percent in class 12th examination. It actually varies from exam to exam. So you need to check all the details before appearing for that particular exam.

Hello, Ankit
Yes, you are eligible for JEE advance if you have scored 71.2% in 12th but just securing marks in 12th will not work as you need to clear JEE mains first and then you will be able to sit in advance paper.
BEST OF LUCK FOR FUTURE.
