my school doesnt care how many adv highers you take. my maths teacher also told us we shouldnt take any unless unis ask for them or youre gonna do that subject at uni or smth.
i took higher maths, english, modern studies, biology, and chemistry last year + this year im taking higher business, geography, rmps, and history. no adv highers. i wanna do primary teaching so i think its impressive to have a wide range of subjects at higher.
