@thumper1, the top rigour courses he can take are AP courses and he is taking AP courses, he’s just not taking every AP course available. How many are enough taking into consideration that the bulk of them are only available in senior year? He will graduate with 8 grade 12 credits but only 6 are required under the Ontario curriculum and 4 of them will be AP. Of the other courses he is planning on taking he could take his grade 11 & 12 English credits at the AP level but has opted not to. He could take AP US History in grade 11 but prefers to take World History instead and it is not offered as an AP course. The remaining available AP courses he could take are not in subjects he is planning on taking at all (AP French Language, AP Psychology, and AP Biology). Does that mean he should be taking them just by virtue of them being AP courses?
