Is it really recommended to submit ALL SAT II scores?

<p>I took the SAT Physics and Math II this summer but was unsure of how well I'd do (especially in Physics, but I didn't prepare much for either) and so I opted to not submit any of my scores to any colleges. Well, it seems I was right, as I did alright on Math II (780), but not so well on Physics (630)...</p>

<p>However, when I look at Caltech's website, its "strongly recommended" that all scores are submitted. Now, obviously I'm going to retake the Physics test, but would it really be better if I was to submit both scores rather than just the October one? (Side question: Can I still apply EA if I take the test in October?) </p>

<p>Thanks</p>
