Degree

Hello Abinaya,
It's very nice to know your dream of doing PG in engineering even after so many years. You need to take GATE of the subject in which you want to do PG. I would advise you to have a look at different subjects available and then select the subject that fascinates you.

Hi, yes there are courses in Oil and Gas, Oil Drilling etc. Not sure about a Masters but check these schools if you can find anything useful
Canadian Drilling School
Mount Royal University
CDI College etc

Of-course you are. For any Masters in hotel management, you just need a Bachelor degree in hotel management.

Hello Mohammed,
It's very nice to see that you have a dream of doing Masters in engineering. But to realise dreams one has to take efforts. You will have to appear and score good marks in GATE if you want to realise your dreams.

For getting admissions in LLB, you need to give the entrance exam of law which is CLAT. I'll share with you the important dates for this and colleges where you can apply as well for this course.
You can plan your dates accordingly and apply to the colleges which are well recognised for their degree in law:
NLSIU, Bangalore
NALSAR, Hyderabad
Campus law centre, Delhi
Symbiosis Law School, Pune
UPES, Dehradun

UGC takes NET exam through CBSE. the next attempt in 2017 will be taken by those who have applied for that. last date has gone. You need to be a Post Graduate in a subject Listed by UGC for NET. States also take their own exams like SLETs. for that you need to keep checking which state has opened the test. with SLET, you will remain eligible for that state only. with NET, anywhere in UGC approved college you can go.
