<p>You have time to improve your SAT score. If you plan to take SAT II in October, it’s not late to take SAT in November. It’s OK if you don’t want to study for it, if your Math is really good. I assume it because you aim an 800 at Math 2. I don’t think CR and Writing matter too much at Caltech, but Math does. You’ll only lose one day of your busy life, but it’s worth.</p>
