Help me decide whether to take SAT Subject Tests or SAT I!

<p>I have a few more days yet until the late-registration deadline for the October SAT. My question is: should I take the SAT I or the SAT IIs?</p>

<p>I'm applying RD to the places that require the subject tests (Carnegie Mellon & Princeton), so I technically have three more months (aka 3 test dates) to fulfill all the required testing. I've taken the SATI once and scored a 2200. I want to take the SATI again and see if I can raise my score (2300+), and I still have to take the SATIIs. I've decided to take the Literature and MathII subject tests, and I have to study a lot for the MathII still.</p>

<p>So here are my options
(Oct, Nov, Dec):</p>

<p>(SATII, SATI, SATII) benefits> Time to see if I should even take the SATI in November, because by the time November comes around, I'll know my second ACT score (first was a 33). Time between SATIIs so I can evaluate my score and see what I did wrong.</p>

<p>(SATI, SATII, SATII) benefits> More time to study for the initial SATII test. I'm required by Carnegie to send all SAT tests I take, so this strategy might help me avoid lower subject test scores right off the bat.</p>

<p>What do you think I should do?
Thanks.</p>
