M.Sc

Hi,
Yes, you can appear in IIT JAM exam for M.Sc. Admissions. Make sure to check all eligibility criteria and syllabus of the exam for your subject before applying to the exam.

The college says as 40k academic fees per year for this 2 year course. It is not inclusive of the accommodation/hostel and other non academic fees as per the admission procedure. Saying "give fee", I believe you just refer to the academic fees. In addition there are some consumable charges/fees charged by the department on account of lab materials used.

The diploma wouldn't fetch you much, especially a distance one. If you really want to make career in Astronomy and AstroPhysics, you should rather opt for M.Sc and PhD.

Yes dear, you are eligible. The minimum marks required is 50 % to qualify.
