<p>I’d be very cautious about taking MENU. I mean, if he is really, really really (and I mean REALLY) invested and in love with math, then go for it.
I took calc ab and got a five on the ap, and was invited to take MENU. I ended up not taking it, and I’m so glad. It’s VERY hard, as in, mostly people at the graduate level in other universities would be doing the sort of stuff they do in MENU. Be very careful about choosing MENU, and be sure you’re invested in it.
That said, the people who are in MENU either love it or hate it, and if you’re one of the lucky few that is incredibly talented with math, I’d say go for it!</p>
