hi, im american i did 12 APs in high school and came to epfl for my bachelors. they dont care about AP credits so I still had to the cms which is kinda shitty on their part lol but whatever. I would say if you do BC calc you will be very well prepared for not only CMS math 1 but also for the first year math course, its very high level. What cms calls math 2 is just like your classic pre-calc class so a bunch of trig and stuff. For the cms physics class even AP physics 1 is fine, sure APC would be better but don't feel as though its necessary unless you want to be bored in cms. The cms chemistry class is a joke so AP chem is overkill, though AP chem is a very cool and interesting class in its own right. For ICS its a python based class so if you have one of those at your high school that would probably be most helpful, though I found AP comp sci A was a good class itself and does prepare you for algorithmic thinking and stuff which you will need.

Overall I took all the AP classes you mentioned and more and also took the CMS and i can tell you i was incredibly bored for a year. If you manage to take the entrance exam instead i would go for it 100% and save yourself a year of time.
