I failed in +2, qualified BPP (Bachelors in preparatory programme) from IGNOU and completed BA in English Major with 61%. Can I do D.El.Ed?

Yes, you can do D.El.Ed. Later, you can do your D.Ed also. But, you are advised to clear your +2. Otherwise, there will a big gap in your learning .If your learning is incomplete, how will you help your students in future?
