I like stats. Not dissing stats. Just comparing what we are doing now to the stats class I took...he might fall asleep. LOL
I agree that this is a real possibility, and I would suggest that he talks to the professor about it. It really depends on how much he already knows about stats, what the other students are like, and whether there's a better stats class he could take now or in the future (e.g. if he majors in STEM, this class likely won't count towards his degree (other than as general elective credit, which he may or may not have space for anyway), and he would likely need to take some sort of upper division stats class, so, it would quite possibly be a waste of time/money).
And I agree that stats and probability is important. I just don't know if this class would be a good fit... but I don't know much about your son (nor this specific class... just about the 1000 level stats class I took in college).
