I need to pick 2 of Physics/Chemistry/Biology

I’m going to do the maths II, so I can only take 2 more SAT subjects as I don’t want to do more.

I’m tossing up which 2 to do, I have scored a terrible score of 500-600 in the physics and chemistry but I’m confident I can bring it up with study! I think I’ll score around the same for biology too.

My question is that, is a 700/750 on like physics/chemistry/biology more impressive? I heard that biology is seen as less rigorous and hence, as an international student I would probably want to “show off” more by taking harder subjects?

Love to hear any thoughts - thank you~

Having 3 subject tests will be enough regardless of the test name. Do what comes easiest to you and do it well.
