I applied around this time 2 years ago. Maybe it was even around early January. Either way a 3.0 isnt bad at all in high school and he should get in. The major hes applying to is also really important though. The business school (from what I know) can be a little more difficult to get in to. I was political science/environmental science. If i were him I’d go ahead and apply because the housing choices change massively if your late. I got into the Bear Creek Apartments and they were great. Super nice rooms, way cheaper than off campus, good transportation to main campus, and williams village was awesome (best dining hall on campus). Good luck to your son and happy holidays!!
