<p>"Happy" new year guys! (espacially for upcoming seniors! Cheers!)</p>

<p>I just took SAT world history and am planning on self studying AP world history test. I am also considering taking all AP/SAT chemistry, AP/SAT US history. </p>

<p>Do they look good together in the application?
And are they very different? I mean, I got 800 in SAT world history. Do I need to study for AP test separately? Do they cover lots of different things?</p>

<p>The AP test has 3 essays you have to write as well, so it's a little different.</p>
