B.Ed

The minimum eligibility criterion for admission to B. Ed. is that the student must be a graduate in any discipline. The candidate must either have a Bachelor of Arts (BA) or Bachelor of Science (B. Sc.) or Bachelor in Commerce (B. Com.) from any recognized university with at least 50% marks in aggregate.

The decision taken by DEC was communicated to UPRTOU vice-chancellor Prof AK Bakshi, who said a student cannot enrol for two-degree courses at the same time. However, he added that students can do the same through distance or combination of distance and regular modes from the same or different institution.

You need not do D.El.Ed after completing of your B.Ed. After completing your Master's degree, will you do your graduation again? B.Ed is Bachelor of Education and D.El.Ed is Diploma in elementary education. You should not opt for UG course once you are done with your Bachelor's degree.

If you have any doubt, let me clear it. Anyone can obtain a degree from any university within the country. Similarly, everyone has a right to get a job under any state government. It is our right to freedom. Now, if you have completed B.Ed from Andhra University and want to do a job in Odisha, there will be no obstacle, go ahead.
Good luck.

Both are good options, you can do B.Ed after your graduation but D.El.Ed just after your 10+2. With B.Ed, you can apply for both TGT and PGT. But for PGT you need to complete your Master's degree. D.El.Ed is a Diploma course. So with this, you can apply for the elementary level post that means from nursery to class 8th.

You are eligible to apply for B.Ed.
The eligibility is you need to have with at least 55 % marks either in the Bachelor's degree and/or in the master's degree in Sciences/Social Sciences/Commerce/Humanity, Bachelors in Engineering.

Mostly the colleges offer admission to students who have passed the course from UGC approved college.
AICTE college will grant admission or not is totally at the college discretion.
