Hey there,

Dear candidate hope you are doing well, first of all you need to know that M. Sc in physics will give you opportunity to study both Physics and Mathematics. But if you opt for MSc in mathematics then you are only going to solve mathematics for the two years. Also so there is one more factor that would decide which subject you should go for.

The factor is that in which subject to have done your bachelor's degree if you have done your bachelor's degree in physics then it is appropriate to go for MSc physics but if you have done done your Bachelor's in mathematics then you can go for MSc mathematics.

Also so you need to think that with subject you are more inclined towards if you think that you are interested in mathematics and you are very concerned about it then go for it. I hope this solves your concern.

Thank you!!!
