Same here with DS
We have a nice organised list in the iphone notes app which is shared between me, DW and DS. We've checked off everything in the 'shopping list' area - bedding, towels, crockery etc etc. Even new laptop.
He has a section for 'register for Uni, upload photo etc - basically uni admin' - almost nothing is checked off. If we ask, he might mention he has done X or Y but doesn't update us without prompting, and its starting to feel like we're nagging.
He should be way more proactive. I guess he's trying to take advantage of the last of the summer hols but its been a massive break since A-Level exams so he needs to get off his arse
