Lol, you aren’t “interested” in FL? Then hone a list of colleges that don’t expect to see he full course of it. OP cited an interest in, “Berkeley, Stanford, Yale, Harvard, MIT, and Cornell.” If they recommend 3 or 4 years, you either provide those basics or not, at your own risk. Shorting FL is one of the easy flags even a top performer kid can get. You do get to pick your targets But they choose you- or not.
OP did research some of this, yes. But still wants to opt out of Span 3. Many of us feel that’s not wise. Not for those colleges, where the competition is immense. It is not as if he’s dropping Span for math or science classes past AP. Yes, he can take the online course his hs approved.
OP also referenced how Span 3 will affect his gpa. Fine, he wants to be val. But he should be making wise choices if he wants an uber competitive Tippy Top, at the same time. Or, revise the list. Val is a high school honor, not a guarantee or hook. For most kids on CC, the goal is about college choices and bettering their shot.
