My daughter's choice of subject is the same as yours.
How's your daughter M1 result?
always fail?
If she put much effort on it, the result will not be too bad.
If she does not aim at getting into the university with M1 required in certain subjects, you can tell her to drop. It's ok.
Anyway, I think studying M1 seems better than those students only study 2x/3x. It is safer to have more choices in university.
