Dear,
If it's your choice to join government college then IITs and NITs are best. But, if you want to join Private college and want some good package then LPU will be best for you.

Hi dear,
Mathematics branches out to various areas in higher studies from data analytics to statistics to finance and what not. It would be difficult to type all possible opportunities here so take a look at this article from my e-library:

Yes, Your degree is valid according to UGC guidelines. You can appear for competitive exams and all. All the best.

In the last round of the cutoff marks, if there are vacant seats left, then you can easily get admission, but if not, then you can't get admission in that, but the chances are that you will get the admission.

Hi, yes there is entrance exam for M.Sc maths in Thapar University.

IGNOU is better than KU. Another option is Annamalai University.

As per my knowledge and experience, for getting a good payable job, you must go for M.Sc Mathematics as there are many good opportunities after completing this course as compared to M.Sc Chemistry.
