Our DS got the grades he needed and a place at his first choice Uni but was still completely disengaged and didn't do a single thing to prepare, didn't even pack, he had no interest at all. We had to do it all for him, otherwise I don't think he'd have bothered going. We even unpacked in his Uni accommodation, set up his room, made his bed, etc.
3 years later, he graduated with a First, straight into a top graduate scheme in one of the UK's biggest financial firms. He didn't engage with getting a flat in his new work town, so we ended up doing that for him too, bought him furniture for it (he couldn't get a furnished flat), moved all his stuff there and set up his flat! Same story really - in complete denial.
However, after 2 years, he wanted to move, sourced his own new flat, sorted out end of tenancy with landlord, end of tenancy cleaning, removals firm, etc., and basically did it all himself. After another year, he moved city to a different job, again sourced his own cleaners, flat, removals, etc - we havn't even been to his new flat as its hundreds of miles away. Just grateful he's finally got his head in gear and doing things for himself rather than being in denial.
I think the OP's lad will find his own way at Uni once he's there and they're probably worrying unnecessarily. Some just need a lot more help/encouragement than others.
