I’m assuming son’s books are free, as a D1 athlete.
Re: athletic tutoring, @imwiththeband has set forth some great suggestions, and as an insider, he/she surely knows about this.
My question to @imwiththeband: our experience with two colleges with the athletic tutoring was, sadly, substandard for a lot of reasons I’m not going to go into - but most particularly in the math areas as students got into the higher math subjects. Has it been your experience that for the (probably, relatively few) D1 athletes who are taking higher math subjects (calc 3, diff eq, linear algebra and beyond), it is better to find a private, experienced, non-student, AVAILABLE-at-odd-hours tutor to keep them up with missed classes? That was 100% our experience, but I’m sure it varies greatly from school to school.
Regarding tutoring at all, I think it’s really something the athlete has to agree to do. You can’t push it on him if he just refuses (and yes, he will learn the hard way if his grades are bad). One of my kids was at a college where the culture on his team that particular year was to pooh-pooh anyone who needed a tutor, and this did not end well for some of the athletes who needed it, and were ultimately ineligible to play due to grades. Hopefully, your coach is keeping a close eye on the kids’ grades. Not all of them do. That said, you have to leave this to your son, and just brace yourself for the worst, perhaps a bad grade or two this semester. If that happens, don’t overreact, it’s just one semester and the lesson learned (i.e., get help when you need it) will last a lifetime.
The biggest pushback we faced re: tutors was that kids come back from their trips really, really tired and facing a mountain of work they have to catch up on. They think: “hmmm…I can go see my tutor/professor/peers and spend some time catching up on all this … OR, I can spend those few extra hours SLEEPING and just wing it on my own.” For some kids, it takes the bad experience of trying to wing it - and getting bad grades (or worse) to realize that they do need to carve out a few hours getting some extra formalized instruction via tutor/office hours, etc.
I am in the camp of people here who think your son will figure this out on his own. Believe me, he has been well informed of all of the academic assistance available to him as an athlete, and if he is unwilling to avail himself of it, you hounding him about it will not change that.
I really like your attitude, OP! Please stop worrying about things you CANNOT change. Enjoy the ride! I am all about academics too, but I also think that these young people are only young once, and these opportunities only come once. Not everyone can play a D1 sport. This is an honor and a privilege that will give your son memories and experiences that will last a lifetime. Employers LOVE athletes; there is value to this beyond a gpa if he can survive it.
Stay out of his way! Follow his lead and support him. His ride will end all too soon, for all kinds of possible reasons: he will graduate, there could be injuries, and yes, there could be academic (or other) ineligibility. Is this a reason for him not to “go for it?” NO!!! Sure there could be regrets, but these need to be HIS regrets. Last thing you want is for him to think back on all this and remember how YOU tried to interfere.
