<p>Should I take 2 or 3 Subject Tests? I'm debating between taking Math II, Chem and Physics or Math II and Chem. I took Chem last year so I'm good with that. However, i've only taken a semester of Physics. ALso, what prep books should I buy to study for them? I have PR for Math II.</p>

<p>You have nothing to lose by taking three subject tests. However, if studying for a third will negatively impact the amount of time you put towards studying for the first two (Math II and Chem in your case), then it may be a hindrance rather than a benefit.</p>
