Teaching experience is not a condition to get admission in B.Ed. So you can apply for that without any hesitation. You can choose IGNOU as it a trusted university for distance education. Remember, for admission in B.Ed, 50% is required either in graduation or Masters.

Hi,
Eligibility: A graduate (10+2+3) in any discipline with at least 50% marks (45% for SC/ST) from any recognized University.
With your graduation score you will not be able to get admission.

Dear,
You can't do B.Tech through distance/part-time or correspondence. However, you can study AMIE course. AMIE is an engineering programme run by the Institution of Engineers, India. This course is specifically meant for people like you who are working after completing Diploma. The institution of Engineers is a central government organisation.
You don't need to go to any college or attend any classes. Find an Institution of Engineers branch in your locality. Use the internet for this. Enrol yourself. Rest, they will guide you. It's a flexible course you can finish papers one by one or as per your wish.

Evening or distance engineering courses are not valid any more as per the latest Supreme Court verdict. Hence, I would recommend you to join regular B.Tech course for better career prospects.

The courses offered by IGNOU are well recognised, not only in India, but in other countries also.

You can get admission in IETE or AMIE.
