<p>The math, as a parent, doesn’t look particularly difficult but son is now transitioning to Exeter in the more challenging math while attempting a 300 level class in CS seems risky. </p>
<p>The 300 level courses are for uppers and he might be biting off more than necessary at this point especially with APs, PSAT and possibly SATs. It might makes more sense to take it once he eases into the higher level math and make a comfortable transition. Let me know if it would be wise to push back on taking CS later.</p>
