Yes, you can definitely pursue a Master's in Geography (M.Sc. or M.A. depending on the program) even with a B.Sc. in Physics, Chemistry, and Mathematics.

Many universities offering Geography Masters programs require a bachelor's degree from a recognized university, often with a minimum percentage (around 50%), but not necessarily in Geography itself.

The strong foundation in quantitative subjects like yours can be an asset in Geography. Geography uses statistics, spatial analysis, and modeling techniques that directly benefit from a math and science background.

Overall, your B.Sc. in Physics, Chemistry, and Mathematics provides a strong quantitative foundation that can be a great asset for pursuing a Master's degree in Geography.

I hope it helps!
