I started off with 2, but ended up dropping one...i'm really glad i did b/c i was super busy and having homework for one class was enough for me to handle lol. but it's totally possible to take 2 and be fine, it just depends what class u take i think. i didn't do any of the exploration series classes (i did creativity & innovation which was really good...dropped human resources) so i dont know if they have homework or not
