<p>I have decided to take 2 SAT subject tests this June out of US history, Chem, and Lit.</p>

<p>If I were to take USH and Lit which one should I take first? which is more exhausting?</p>

<p>If I were to take USH and Chem, which one should I take first?</p>

<p>USH is a must. I'm still debating whether to take Lit or Chem. </p>

<p>Any suggestions? </p>

<p>and does anybody know a good prep book for AP Lit?
I have Kaplans sitting around at home that my sister used to use, but I don't know how accurate it is.</p>
