<p>I took the Math II, Physics, and US History Subject Tests in October, and did a lot worse than I expected to with scores of 750, 700, and 720 respectively. I'm scheduled to take the tests again on November 1st. I'm interested in an engineering degree, so I'm definitely retaking the physics (since I performed so poorly on it), but I only signed up for two tests in November, as I thought I had done really well on US History.</p>
<p>My question is: Which of the other two tests should I retake if I would like to go to an engineering school (basically I'm wondering if the Math II is high enough or if I should hardcore study and get an 800)? And if I send these scores to the engineering schools I'm applying to early action (currently MIT, and Caltech) will they get them in time to affect my admissions chances?</p>
