<p>I only could take one of the two. I scored a little higher on US history than Bio on a practice exam. 610 on US and 580 on Bio. But, I luckily guessed some US questions right.</p>
<p>Which one involves more memorization?
Which one requires a deeper understanding? (like applying to situational problems)</p>
<p>Thanks so much for your help!</p>
<p>I’m better at science than history so I would pick bio. I feel like one needs to memorize more facts for U.S. history, whereas bio sometimes involves the application of broader concepts. But it’s just a personal preference.</p>
<p>Also, some people want to take one science/math and one humanity SATII, so I guess if you want to do that what you decide now would depend on what your other SAT is going to be.</p>
