<p>if I were you, i would immediately sign up for SAT Math 2. Yes, the test is not until late Jan and scores won’t be available until mid-Feb, but a high score would come in handy if you get wait listed.</p>
<p>The problem that you may have is that some ChemE programs are taught in an Engineering college of a University, whereas the undecideds go to the liberal arts College of the same Uni. However, it can be extremely difficult to transfer into the Eng college from the liberal arts college. IN such cases, applying undecided would not be a good move.</p>
<p>wrt questions: you should not address your math score. Instead, let your GC address it. Or better yet, get a strong rec from your Calc teacher.</p>
