I am commerce student with math and I want to do bsc hons mathematics so how will I study physics and chemistry in graduation ?
Your case is very common for commerce with maths student who want to pursue bsc hons mathematics.I know the procedure followed by Du , if you have taken an hons course then there will be a generic elective subject and that you can choose yourself such as history , eco etc.And in 3 rd yr there is no GE.
Hope it helps.
Best of luck.
