I hate to be harsh but here are a couple of “truths”.
You can either afford the college or you can’t. If you can’t- your son needs to find a more affordable alternative for a sophomore year transfer.
He’s either finding college easy or he’s not. If he’s “underperforming” and not completing assignments on time, etc. he’s clearly NOT finding it easy despite what he may tell you. He may get a total shellacking come finals. I remember my freshman year classmates who’d brag how easy college classes were compared to their “gifted” programs, elite exam high schools, prep schools, etc. and then us regular, “ordinary public high school” classmates would wipe the floor with them. My HS had over 1100 students in my graduating class- many of whom went straight to the military (despite a very unpopular war), a trade school program in auto repair, beautician school, etc. I had no illusions about how rigorous my HS was so I decided early on to just outwork everyone else. Professor has a “suggested reading list” in addition to the required stuff? A suggestion IS a requirement once you get to college.
His EF coach is either helping or hindering. You need to figure out which it is. Doesn’t sound like a very successful partnership between your son and the coach but you haven’t posted enough information for any conclusion.
Getting all A’s in college is an inappropriate/not helpful goal IMHO. The goal should be academic and intellectual and cultural and artistic “stretching”. Get a B in a tough seminar on “Income Inequality” team taught by a professor of poli sci and a professor of economics? That could be a fantastic outcome if your kid had to work hard to keep up with a thousand pages of reading a week and produce a paper, with index, citations, and original analysis of a large data set in order to fulfill the assignment. Get a B minus in a music theory class where your kid had to learn an entirely new vocabulary, notation system, AND become proficient in two different historical genres? Sounds like a win to me. Etc. You see where I’m going.
A kid blowing off work to socialize may or may not have anything to do with his learning issues. Plenty of kids do that. But I suspect your kid may have had significantly more scaffolding in HS than you guys are aware of or will admit to. THAT’S likely the issue. Did he get himself to the school bus on time every morning? Make himself lunch and remember to put it in his backpack? If he forgot his sports equipment did someone drive it to school or would he have to sit out practice that day? If he handed in an assignment late was it an automatic grade demerit– or were teachers constantly giving makeups and extra credits?
Hugs. You’ll figure this out. But kids who need to get all A’s in college are often kids who are learning the least. They learn to coast. They learn to take the easiest classes. Is that what you are paying for?
