Hello,

A PhD course is usually of three years duration. However, the course duration may vary from one institute to the other.

The eligibility criteria to pursue PhD is that the candidate must have a master’s degree.

In a PhD course students need to select a topic or a subject and do in-depth and extensive research on it.

Also Degrees granted for Doctor of Philosophy (Ph D) programs done through distance education will not be recognised, said the University Grants Commission (UGC) in a circular in the year 2017.

Hence you can't pursue PhD through Distance learning.

I hope you find the answer helpful.

Thank you.
