Most colleges ask for proof of more than the bottom line figure of fees and accommodation as foreign students don’t have the opportunity to work and some colleges offer work but than the student doesn’t see that money as it is used to pay of some of the college fees. Didn’t apply to us but be careful on that front.
@MYOS1634 says the way of grading is completely different than UK unis. Every unit counts. Really suited my son as he didn’t do so well on a big exam at the end. Worked much better in smaller chunks about every 7 weeks or so but there is no ‘messing about’ in the first year where it is just a pass or a fail.
Going in at 21 again won’t be too much of a problem as many classes can be mixed but if he is living on campus for the first year he might feel a bit of an old boy. Also while he will be able to drink - none of the his friends will be able to join him in bars - though they will love him as he will be able to get the beers in as they can’t.
