Physics Spl

2 years M.Sc. In Reva University would cost you around 3-5 lacs, and if you are from sports or any scholarship claiming quota it might be reduced.

You know what, Physics itself is the application of maths. Think about which kind of engineering you like. Choices are temporary. You might be hating it now but can love it on later course. In every domain of engineering you will find physics. In fact engineering is a practical course. Think which thing fascinates you.

You can do two things again get back on your track of JEE with more hardwork learning from your failure but it's more advisable to get admission in private engineering college. More important is to do B.Tech. If you are passionate learner you can get success in any college. So don't lose your hope.

Actually you can't do like this. If you have Masters in maths then cannot go for Ph.D. in Physics without Masters in physics. Similarly you should have maths as core subject to do M.Sc. in maths. Chemistry honours students cannot do maths honours if they don't have maths.
