SAT II Physics?

<p>I'm a current junior with no previous physics knowledge but I will be taking AP Physics C: Mechanics starting next fall of senior year. I'm most likely to be applying as an engineering major, and I know many schools (such as Penn Engineering) strongly recommend SAT II Physics for admissions. Is it worth spending extra time (most likely a good amount of time) studying for the SAT II Physics exam? If I am taking it, it will likely be November of my senior year. I'm aiming for at least a 750 on any SAT II I take. I've already taken SAT Chemistry and Math II, 800 on both. Any advice would be greatly appreciated.</p>
