math IIc and physics

<p>if i already studied for and got a 720 on the math I c, what extra preparation do you think i need to do for the math II c?</p>

<p>also, i'm in ap physics b now...and am getting an a. is the physics sat II very hard? should i only take it after i took ap physics c?</p>

<p>also, if im taking the ap US test, would i need to study any extra for the us history sat II?</p>

<p>thanks a lot!</p>

<p>i got 750 on math I and i'm hoping to get 800 on math II C . i think you can get 800 too with a little preparation ( check sparknotes ) </p>

<p>i'm taking physics too after 5 weeks but i really can't work out what there'll be in the test. they say physics is not that hard but i don't know..</p>
