Should I retake subject SATs?

I gave the May 2016 attempt. Got my scores today. I gave the Physics,Math level 2 and Chemistry subject SAT test. My scores are as follows:
Math Level 2 : 800/800
Physics : 720/800
Chemistry : 740/800
Im looking to apply for Computer Engineering to schools like University of California Berekely, UCLA, Purdue, Stanford, Cornell, Carnegie Mellon,etc. Should i retake the Science subject tests?

Can someone please reply!

S1 was accepted to Berkeley and UCLA for Computer Science (not Computer Engineering) with the same SAT Math 2 score and a lower Chemistry score. He didn’t take the Physics test. From the experience of one of his classmates, I got the impression that the UCs are more particular about GPA than test scores, and that Carnegie Mellon is more flexible about GPA. I don’t know if you need to retake or not because Computer Engineering seems a bit harder to get into than Computer Science. My guess is that the Chemistry and Physics scores are fine and that your admission will depend on the other aspects of your application.
