SAT subject tests!!

<p>Hi, I just took 3 SAT subject tests last Saturday, but I don't think I did well on 2 of them (probably low 500-600). I think I did well on the 3rd one, and I want to send it to my colleges, but I know I can't cancel the other two scores without also cancelling the good one. I have already taken two subject tests in the past, and one of them was a good score while the other was a 630 (not as high as I wanted). I retook subject tests in hopes of improving these scores, but I think the only one that will be replaced in terms of my highest scores willl be the 630 one. A few of my schools require me to submit scores from all tests I take, and I'm scared that they will look negatively upon my lower scores. I was wondering how much subject tests matter overall, and if colleges (ivies) will only use my highest two scores to make the admissions decision. Will they take into account my lower scores when I send them all? Should I cancel the scores from my recent test and allow them to use only my previous test scores? I'm basically confused and scared about the overall weight that is given to subject tests... I believe my SAT score was pretty good, so will submitting all my sat ii's (ok ones and bad ones) ruin my chances?</p>
