UBC International High school student CS requirements?

Hi, I am a senior right now and I just realized that UBC requires students to take AP chemistry and AP physics to even apply for their computer science major. I wanted to know if this was true? And if I haven’t taken this courses yet, I can’t even apply?
I’ve taken AP biology and chemistry honors, and right now taking AP environmental science instead. Since it is the start of the school year, should I switch out of APES instead and double the two classes? (AP chem and AP physics) I’m very worried about the workload.

Extra info:
I have dual residency in Canada and America (I was born in Canada)
This is my schedule for senior year:
AP Lit
APES
AP Comp sci
AP Macro
precalc
no sixth period
