<p>I don’t know that they have an upper limit…just know you need approval for >18.
The “freshman honeymoon” wore off for D1 this year as she started sophomore year…with all her AP credit, she’d completed most of her CORE requirements, so she was big-time into classes for her major(s) both semesters this year. Of course, she’s always been way rough on herself, but she’s freaking out about her 2 hardest finals coming up next week. If your son thinks he can handle 19, let him go for it! The social scene for sophomores seems to be a bit different, IMO…seems like it’s less random spur-of-the-moment activities with various people on your floor, and more planned things with your friends. He may have a little more control on his extra time next year, too. If he has a gf, just hope she sees the value in studying, too!</p>
