This assumes he has the capacity and maturity to earn the bachelor’s - which he hasn’t yet displayed, has he? What’s more likely:
i) As courses get more challenging he still plows along at the low 2.-whatever GPA to graduate on time.
ii) Has a come to Jesus awakening and surges to the Dean’s list for consecutive semesters.
iii) Sinks lower, to the point of requiring extra semesters or is finally kicked out for low performance.
I think based on what we know thus far, most would lean towards on (iii). Most would say (ii) is unlikely “magical thinking”. And (i) may be possible, but wouldn’t exactly make us thrilled - I’d be worried about his ability to be self-sufficient after graduation. Who would hire him? I know my and my husband’s companies would have zero interest in such an applicant (and we don’t work at prestigious places). If in four years he’s begging us for money, underemployed with a worthless degree and repellent graduating GPA, will we wonder why we continued to waste a large sum of family money when confronted with the most obvious of red flags?
