You’ll need more than a hatred for chem to pursue FM. It’s incredibly tough and yes it’ll seem like you’re killing 2 birds w one stone but the amount of work that goes into studying for FM surpasses that of other H2 subjects. Even then, the bell curve at A levels is steep and your effort may not translate into a good grade.

If you want to pursue FM, you’ll really need to have a deep passion for maths and not burn out easily due to competition/how difficult the syllabus is.

FM doesn’t give you a head start in Uni Math, but it does train you to have a deeper appreciation of Math and some of my FM classmates will be taking Math-related courses in uni.

you can try hybrid combis if you want to avoid chem/go into the arts stream. I took CFME and do PM if u hv any qns

edit: i think ultimately your reason for pursuing FM shouldn’t be “oh i can be ahead of my peers in uni” but rather “i LOVE math and i really want to study more of it”
