SAT Subject Test Scores

I need help regarding my SAT subject test scores. I received an 800 in SAT Maths Level 2 (It was expected), however to my shock, I received a 700 in Physics and a 710 in Chemistry (I expected at least a 760+ for both), this had never happened to me anytime before. I had always received a 780+ in both exams and I had received an A* for Physics and Chemistry IGCSE exams. Now I’m thinking about sending in for an SAT Hand-score verification for my scores. I had taken the exam on the 4th of November. I would like to know whether the Hand-Score Verification is effective and if I would make it till the deadlines for Top-Unis (Caltech,Stanford,MIT,etc.) if I send in for a verification.

If you are sure that you used required material like pencil no2 and a good eareser then make a request for it. Otherwise they dont even bother to do.
