M.Phil Eligibility

Dual degree B.Tech-M.Tech in biotechnology are eligible to seek admission in M.Phil and PhDs.

You can pursue M.Phil while on the job by doing M.Phil from any of the distance learning university. It may be difficult to do a job while doing full-time M.Phil from a university.

MA degree holders from a recognised university approved by UGC are eligible for M.Phil degree at KUVEMPU or IGNOU.

MA is a degree you can get by studying in two ways. One is full time or class based and one is distance learning. However, one can do MA in any domain in distance learning and they can appear for M.Phil/PhD. Since these two are also degrees you can earn by joining into those fields. Where as PhD is the highest degree qualification for a person to learn and to create knowledge in the field one will go for research.
So you are eligible for PhD after completing MA. I hope that above information will help you in one way or other. Have a good time!
