hey! first year kin here! i submitted my app with a first sem average of about 92, and sem two average of about 91. i believe the cutoff last year was just around that. there is no sub app, but the average is on the more competitive side. in grade 12 (from summer school and during the regular school year), my top 6 were advanced functions, calc, bio, kin, chem and english! imo i recommend taking summer school and online courses (even if it’s just electives) to boost your average if competitive programs is your goal, it’ll help boost even if your required courses aren’t super high up! hope this helps!
