should i take all 3 sciences grade 11?

hi grade 10 picking grade 11 courses rn. I cant decide whether or not I should take all 3 sciences (bio, chem, physics) tbh i really dont know what i want to do in the future yet and yeah i like science but i like math more. I would take all 3 but im worried ab the workload and all the stress, i feel like 3 sciences would be rlly hard. I dont think im bad at science but also I got an 86 this year which compared to my other courses is really low and i got higher last year. If anyone here has take all 3 in grade 11 how was your experience? does bio have a lot of memorizing? is physics hard?? I live in ontario btw and if i do take all 3 i will be taking academic.
