Reasoning test or Subject test?

<p>So I'm taking 3 Subject tests (Bio, Physics, Math II) in May and the ACT in June. I want to take the Reasoning test 1-2 more times until I get 2200 or 2250+, but I don't know when I should take it. Also, I'm not too sure I can get a 700+ in Physics because I took the class last year and was confused most of the time due to a incompatible 1st sem teacher. I MIGHT apply to Princeton so if I get a bad score on physics I will retake it or take another exam. Now the question is when should I register for the RT and ST? I find that even if I receive a bad score on the May exam, I would not know until after the June deadline is passed and I do not want to pay TCB the late fee... If I register for the RT in June, I don't know if I'll be able to study enough due to the ACT and my tendency to procrastinate. Also, I'm planning on doing QuestBridge so the Oct test is the last time I can take either I/II.</p>
