<p>I have both Princeton and Barron's. I noticed that Barron's devotes an entire chapter to photosynthesis, but PR doesn't even mention it...</p>
<p>What's up?</p>
<p>You should know where it occurs, what products are formed, and the different parts of it. I don’t think that they’ll ask very specific questions like “What is the second molecules formed in the Calvin Cycle,” but more general ones like “Where does the Calvin Cycle take place-- what does it produce, what molecule is reproduced at the end of the cycle etc.”</p>
<p>I agree with winnar. I remember a question about Photosynthesis last time I took the subject test, but it was too general. Basically, know the basic stuff and you’ll hopefully be fine.</p>
<p>Thanks you two.</p>
<p>So Barron’s is over kill right?</p>
<p>It’s not entirely an over kill, at least in Bio. The Barron’s tests are a bit harder than the real thing, but in my opinion being over prepared if you have the time is not a problem at all. Most people suggest studying using Princeton, though (at least for the Bio test). If I were you, I would study Princeton, take a practice test or two, then review my weak points using Barron’s. Keep repeating until you’re confident with yourself.</p>
<p>Good luck!</p>
