Minimum 3 years and Maximum 5 years.

Sorry to say that Annamalai doesn't offer B.Sc programs via distance education. You can do B.Sc in clinical psychology from Amity Distance University or GMU Italy University.

Yes, you can join the regular classes for BCA. You just need to clear the entrance exam for any professional course such as BCA. It is not beneficial to take admission via correspondence. And for BCA, being a professional course, you should join the regular classes for proper knowledge as doing it via correspondence would not be that much helpful as programming languages are quite tough to learn on our own.

Kuvempu University does not offer M.Ed through distance education. It is a full-time course.

No, you are not eligible for the campus placement, placements are only for regular students not for the correspondence students, but yes you can try in companies by yourself. Good luck.

There is a negligible value of doing BCA or B.Sc from correspondence. It's better to attend regular classes or you must have to go for Master's degree as well from a reputed institute.

As you want to do B.Ed through distance education, then there is no entrance test you can apply online for the registration.
All the best.
