I would suggest you opt for IGNOU rather than any unreliable online institute. IGNOU admission takes place two times a year, the first admission starts July and the second session in January. If you want to take admission in IGNOU, then you can take between March to July and November through January.

Hello Suhail,
Marine Engineering is of course a branch that is in great demand, may be due to good placements after completion of the graduation.

Best wishes to you.

I would say, there is a better scope of M.Sc in Environmental Science, in private or government sector for the environments Science degree holders. You can apply for a research degree in government organization later or may find many lucrative career opportunities in India as well as abroad. Comparatively, Environmental Science will go better.

Indore Institute Of Pharmacy and Smriti College of Pharma Edu, Indore (MP) are the best colleges for Pharma. D in Madhya Pradesh.

Hello,
I think you should approach the agency that conducted this exam in 2018 via a request under RTI. I am afraid what you are seeking is information that is not available in public domain. But, I am sure once you put in request, you will get all the required information in matter of days. Best wishes to you.
