M.A

Hi Nishi,
If you want to take admission in IGNOU for B.Ed, this percentage is not sufficient, because minimum percentage required for B.Ed is 50% for general and SC/ST 45% but you can apply for MA. For that, percentage doesn't matter.
Thank you.

Yes, there is an entrance exam, but it's too late to apply.

IGNOU's degree is at par with any degree of any good university in India. So, you surely can apply for MA in any regular university. But there is a catch. Many universities have norms where they do not prefer students who have done a Bachelor's course from IGNOU so, at the end, it depends on the university.
