Hello Aspirant ,

No , BSc Mathematics (Hons) does not have Physics as a core subject and you will not study it unless you take physics as GE( Generic elective ).

Generic elective is an extra subject a students chooses apart from the core subject , different colleges have different GE subjects for example Maths , physics , chemistry , biology , history etc , you can choose any one of them and change in next semester .

Hope this helps.
