<p>My D took Math 2 at the end of her sophomore year when she had finished Trig/PreCalc Honors. She got a 770. In May she took it over again and scored an 800. An entire year had passed, and she was taking the Chemistry subject test anyway so it was just another hour of testing. She also felt better prepared this time and was happy she did so. To me, a lot has to do with timing. If the question is whether to re-take a 770 in fall of senior year, I’d say no, work on the essays.</p>
