Which SAT II's should I take?

<p>I already took Biology. I scored almost a perfect 800.</p>

<p>I plan on taking Math II and Spanish in June. I also want to take a third test in June, but I'm not sure which one. </p>

<p>I took Chem freshman year, but I don't understand it well.
I'm currently taking Physic's Hon. but I don't think I would do too well.</p>

<p>I'm taking AP English and AP US History as well (probably one of these).
Which one is easier/ more beneficial? I want to break 700. The best I ever got on the SAT I in CR was a 710.</p>

<p>Take US History, it dovetails nicely with APUSH.</p>
