Likewise, if your SAT scores are 800 math and 450 verbal then that's quite uncommon and you probably shouldn't try to be a lawyer but you could still be a quant, and if you have certain medical conditions then you can't be a commercial airline pilot but you could still be a dermatologist.

There's way more to performing in medicine that sat scores.
