No Bio until 12th grade?

It’s not that simple, sunnyschool. Lots of kids are on a fixed track. Lots of stem applicants take physics in 12. And if this is potentially for a tippy top, a lot more than the physics grade is needed- and can show readiness.

But to entirely avoid bio? Must have been an extraordinary humanities applicant? OP’s son does seem headed for stem.

OP, if the GC is ok with this, I think it’s fine to indulge him. Do make sure he has msth-sci ECs snd stretch, but also some rounding.
