i think you should do 4u maths if u wanna do computer science bc its very math heavy in uni. you'll fall behind if you dont know 4u math when u start uni. thats just my suggestion since im doing compsci atm, its up to you tho
i think dr truong cut back and was only teaching 1 class a week for a while and he was focusing on being a doctor. anyway thats just what i heard from my friends
