In taking M.Sc physics you should have studied physics for 3 full years in graduation then you can seek admission in M.Sc physics. Chemistry is not a necessary subject it is counted as an ancillary subject in B.Sc. So don't worry you will get M.Sc physics if you have B.Sc physics degree you can apply.
All the best.

Since you are doing an integrated course, it will take 4 years .Actually, you are benefited in this, as you have integrated B.Ed, as I can see here. You can easily apply at schools at primary and middle school level, if you want to teach or like it .As you know B.Ed had become 2 years course few years ago. You are not losing any way. Be confident on what you do. All the best.

Dear friend,
As per my knowledge and my experience, you are definitely eligible for taking admission in integrated M.Sc chemistry without mathematics because there is no such criteria that you must have studied mathematics as a compulsory subject for doing M.Sc in chemistry or integrated M.Sc chemistry so don't worry about it, you are definitely eligible for it to have a great future ahead. Thank you.

No, it is not compulsory. If you have B.Sc in mathematics you can apply for integrated mathematics.
