<p>^^ Those are the toughest sections, so it’s understandable that you missed some. Make sure you can justify every answer you put with a biological concept. Sometimes an answer is enticing but not biologically accurate.</p>
<p>^ Perhaps he meant to say a waste of respiration. Now that I think about it, I guess oxygen is a waste product of photosynthesis.</p>
<p>O2 is needed as the final electron acceptor in the ETC so even though it’s released it’s still needed</p>
<p>^ That’s in respiration. In photosynthesis, NADP+ is the final electron acceptor.</p>
<p>oh yeah, crap I forgot that. but in general, O2 was the least likely metabolic waste of the choices</p>
<p>Should i take E or M, I do better in E, but I plan on going to a field involving molecular biology in the future?</p>
<p>lol, the test could care less about your future. if you have doubts, you can glance through both sections and pick which one seems easier on test day.</p>
<p>So it doesn’t really matter which one you take, you should just choose the one that is easier?</p>
<p>well, the curve seems to be better for ecology in the barrons scoring guide. you can miss more questions to have a certain score on ecology than molecular. who knows :P</p>
<p>Photosynthesis isn’t respiration, right? So even though oxygen is a product of photosynthesis it’s not a product of metabolism.
Either way, you can rule out all of the others: water is formed at the end of the ETC. CO2 is released at various points in cellular respiration. Amino acids are degraded into urea. And uric acid comes from the degradation of nucleic acids.</p>
<p>^ To my knowledge, metabolism refers to the sum total of chemical activity in an organism. Photosynthesis is a chemical process, just as respiration is.</p>
<p>Yeah, my bio teacher said that question was poorly worded.</p>
<p>So, I got a 780/760 (E/M, took both tests) on Princeton Review,
750-780 on Barron’s,
but a 630 on Sparknotes (though I was half-asleep by then) </p>
<p>How close is sparknotes to the real thing?</p>
<p>Those are the only tests I’ve taken so I’m feeling a bit unsure. I read Barron’s SAT cover to cover today, and I still have some AP Bio info in me… I still can’t help feel so nervous about this. The scoring scale doesn’t seem to be very lenient. ):</p>
<p>I reviewed all of Barrons and took the CB test. 2 wrong, 1 omit. I’ll be stoked if I perform the same tomorrow (this morning?)</p>
<p>THE TEST WAS THE HARDEST I HAVE EVER TAKEN!(two previous official tests and bunch of Barrons)</p>
<p>Honestly guys,if i didnt take AP courses i would do there nothing.</p>
<p>It was twice as hard as previous tests(2011 june or january) and a bit harder then Barrons.</p>
<p>^ At least we’ll get a nice curve, then.</p>
<p>it was very difficult</p>
<p>When can we talk about the qustions</p>
<p>Guys.what is your opinion about curve?</p>
<p>I don’t know, guys. I thought it was pretty challenging. Anyone think we’ll get a nice curve?</p>
