adhd son starting college in fall, advice?

He is 17 and not 18 until July. He had a 29 act and 3.4 gpa. He is an exceptional test taker and is good at music theory and struggles with aural skills. that’s not the problem. The problem is details. Getting work turned in on time cobsistently. I guess the good thing about his medication not be I got as effective is that he now he realizes that he needs it.
12 hours away but we get in state tuition so if he struggles we can still afford the tuition if he loses his scholarship. There were other good music schools but we were worried about losing the scholarships if he got below a 3.0.
pan me for more details.
