Advice on SAT IIs please?

I am a rising senior. I’m aiming for a biology/biochemistry major at UCSD, UCD, or UC Berkeley. I have taken 2 SAT IIs so far - Math II (770) and Chemistry (720).

I plan to take biology in the fall (October). I have a few questions, and I would really really appreciate your input. Thanks!

  1. If I took it in October, would my scores arrive in time for me to report them on my UC app (The UC app is usually due at the end of November.)
  2. Would you suggest I retake Math II or Chemistry? I know UCs don't require SAT IIs, but would these scores hurt my application, rather than help it?
  3. Would you suggest I take the physics subject test? I've taken AP Physics 1&2 this year and will be taking C next year, but I'm not really interested in pursuing a physics major.

Thanks for all the help in advance!
