DS1 lost interest last year as soon as he got an unconditional, but it didn't matter too much as he was accepted to study something unconnected to his school subjects.
DS2 now has a handful of unconditionals (but not from his first choice uni, which sends its offers out in march). He's rapidly losing interest in school, and has mentioned leaving and getting full time hours at his part time job.
This is almost exclusively an issue for Scottish students, and while it's great to know he has a place, sixth year is often a waste of time.
Has anyone else found a solution to keeping their DC motivated in sixth year?
