What scores should I get on math 2 and bio?

I got my scores back and I got a 730 on the Biology and a 630 on the Math 2. I plan to retake the Math in the fall (I wasn’t able to study a lot because of ap testing) along with the Chemistry Subject test. Also, I will likely major in Biology in college. I’m currently interested in Georgetown and UPenn. Is my Biology score acceptable and what should my goal score be on the Math 2? What prep book would you recommend for math 2?

Also, I’m taking the ACT instead of the SAT. Do colleges need to see all of my sat subject scores? Not sure about the rules
