CTET

No, I think you are not eligible for CTET because they don't consider any institute's this kind of certificate. They consider B.Ed, D.El.Ed, B.el.ed for CTET exam.

Yes, you need to attend CTET to be a PGT teacher.

Hi,
The minimum qualification required for entry into B.Ed. course Bachelor of Arts (B.A), Bachelor of Science (B.Sc. ) Bachelor of Commerce (B.Com) form a recognised board/university with at least 50% marks. If you fulfil this criteria then you can pursue regular B.Ed course and you can appear for CTET exam after completing B.Ed.
Thanks.
