Ivys and top 10 admission are a crap shoot. Your counselor may be trying to manage expectations.
Honestly, Bs in bio and calc are more worrisome than a grade in 8th grade. Bs in math and science for a future pre med will likely keep her out of the very top schools. BUT…it doesn’t matter! There are plenty of great schools where your child will get a great education and still be able to matriculate to medical school.
I would also say that your child is taking some of these APs much earlier than most. I would caution you about over acceleration.
