I would suggest he has a word with either the careers service at the college or his tutors about getting a placement for holiday or weekend work. Also have a trawl through the internet and places like the Autosport directory for motorsport outfits based in the local area to see if they could help.
It sounds like a fantastic choice of course and I'll be he's having a great time! I wish him all the best and hope we see him on the telly or trackside soon!
