I'm sorry, jmom2016, that your son's results weren't what you wanted or expected. But I agree with NJSue; the results seem pretty good to me. If the safeties really are not acceptable, however, there is the oft-suggested "gap year." Can your son continue to work his part-time job and take that time to regroup and/or save money to help pay for the highly selective school?
I agree with what others have said about the folly of comparing one student to another. There is no way to know everything about a kid's portfolio even if it were possible to divine what any given adcom is looking for. The only thing we can do as parents is encourage our kids to put their best selves out there.
