<p>@amnovember Well, obviously I know that :P</p>

<p>I meant am I on track if I perform about the same on the free response?</p>

502

<p>I’m new to cc and to this thread, but I too was wondering about the grading system for the exam tomorrow, so I did some searching and found this website:</p>

<p>[AP</a> Pass - AP Biology Calculator](<a href=“http://appass.com/calculators/biology]AP”>AP Biology Test Score Calculator - AP Pass)</p>

<p>although its based off of the old test, its still helpful to see a range of what you need to get a 4 or 5</p>

503

<p>Any last minute cram strategies?</p>

504

<p>@15saintmk: You said it yourself, it’s based off the old test. I wouldn’t put much faith in it: it’s pretty much useless, because no one knows how everyone will do this year.</p>

505

<p>How does your teacher know that an essay will be about signal transduction? And can’t anyone give me the link to the 63 questions the college board released I can’t find them.</p>

507

<p>Yea Cliff’s was way too easy. It was more based of facts than analysis…</p>

508

<p>Does anyone ever do the “relax before the day of the exam and don’t study” thing that’s on like every review book?
I always look at it and laugh because I would never be able to relax before the exam. I’d try to keep cramming more and more info. What about you guys?</p>

509

<p>@15saintmk: the link does not work for me</p>

<p>@amnovember Number 2 made sense. It was straightforward if you looked at it in terms of chemsistry.
Look at this phase diagram:
<a href=“http://serc.carleton.edu/images/research_education/equilibria/h2o_phase_diagram_-_color.v2.jpg[/url]”>http://serc.carleton.edu/images/research_education/equilibria/h2o_phase_diagram_-_color.v2.jpg&lt;/a&gt;
Water stays at an equilibrium between two states, liquid in gas. That’s why it evaporates. In a closed container, water will evaporate into the air in the container, but at that certain temperature, water has a specific vapor pressure which is the amount of water that can be in the gas phase. On the pressure diagram in the link, this represents one of the lines on the chart where the phases are in equilibrium, you can’t get more water to evaporate, since the vapor is pushing down on it.
Now since the plant is in an open environment, it does not stop transpiring, but the forces around it prevent the rate from increasing.</p>

511

<p>do we have to know about the parts of the brain?</p>

512

<p>How are you guys cramming last minute?</p>

513

<p>How much do we have to know about meiosis and mitosis? should we know each stage?</p>

514

<p>@Stargirl794 you don’t have to know the names of the specific phases, but you should have a general sense of what happens in each and the differences between them</p>

515

<p>Can someone really smart post what they got on the collegboard MC questions? :)</p>

516

<p>For cladograms and phylogenetic trees, how do you know when one clade branches off from another? I can easily make a cladogram with just one line and a bunch of other lines sticking off of it in the right order, but many times the correct answer has some branching off of the branches… How does one know that?</p>

517

<p>How do you write a FRQ response? My teacher never taught us about it.</p>

518

<p>@tigerchild</p>

<p>Well, I came in top 150 in the country on the Biology Olympiad this year… USABO and I got around 85% on the new Exam MC. That is down from about 91% on an old released exam…</p>

519

<p>Is it just me or does the 4th Edition (New) Cliffsnotes have unnecessary information? Like, most of the details it goes into are somewhat superfluous… I was not taught this much detail in my class… Anyone have any idea?</p>

520

<p>Is anyone else thinking that the FRQ are going to be really hard? They’re going to count for 50% of the score!</p>
