A PG year is a great option if that makes sense financially. My son is doing one right now but it has nothing at all to do with poor grades or with improving them. With the OP's son's grades as posted, he wouldn't need to improve grades but it would give him another year to go through the recruiting cycle if some doors have closed for this year as it is so late in the process. I would tend to agree with you Lefty, 150 points is a lot to put on unless there has been some tutoring, etc.
