Just went through this with our 24 RHP. The point above about the baseball skill set seems worth repeating. If your son is likely to be a top recruit at one of the ivies that prioritizes winning, rigor will matter a lot less than you might expect. We were really surprised by the reactions to son’s unexceptional transcript. On the other end of the spectrum, even a top recruit at the ivies that focus a lot less on winning should assume that he’ll get little to no bump from baseball.
For whatever it’s worth, we were also told to expect the ivies to remain “test optional” - son almost committed for that reason alone to avoid having to study and sit for the test.
