<p>Chem isn’t too hard, but you cannot make mistakes if you want to get an 800 (I ended up getting a 790).</p>
<p>I’ve heard that Physics is really tough; that’s probably why there’s such a huge curve. I think you should take some diagnostic tests for both Physics and Chem and see how well you do in both, as well as what areas you would need to improve on in order to get a better score. Take the one that you do better on/don’t have to study as much for.</p>
