<p>Okay, am I the only one that thinks the transpiration FRQ was RIDICULOUSLY difficult. I would have never been able to answer that during the actual test…</p>

<p>That one was all about water potential, it had nothing to do with plants. I realized that after I realized what they were asking, and then it was straightforward from there.
But am I the only one who thinks the MC was very difficult, as I got a 72.5%, and most people here are saying they got close to 80%.</p>

<p>How long should a healthy “long” free response be?? I just want to know to what extent I can provide a bunch of information.</p>

<p>And the frqs are very unstructured. There are so many points in the rubric that would be hard to think about during the actual test. I have physics the same day… This is gonna be fun haha</p>

<p>yeah the cliffs explanation for the transpiration experiment didnt even address the topic lol</p>

<p>I was wondering what people think about that. I answered #2 as a practice response and did in about 20 minutes, although couldn’t exactly because things would pop up in the middle. But I wrote about 3/4 a page for a, a little than a 1/4 of a page for b, 1/2 page for c, and 1/2 page for d. So I used all the lined pages for that questions, except only wrote 3 lines into the last page.
The grading is so vague I couldn’t really grade it that well. I tried to read the criteria carefully and apprently you just have to hit point from each category, but its so open ended, how are they supposed to grade it, if you say something not mentioned on the grading criteria or word it differently.</p>

<p>Yeah I agree. I am kind of worried about how anyone will know exactly what to put. I mean they should at least ask us for the recombination frequency instead of just saying to perform a chi squared test.</p>

<p>I’m pretty sure if you word it differently it’ll be alright, and usually if its not mentioned you won’t get points unless its absolutely relevant and makes sense (but I think CB makes a point to cover every correct answer possible). I guess it really depends on the grader. I feel like they just want to see that you understand the concept and know how to answer it with reasonable and related facts.</p>

<p>honestly its not that bad…i got 10 of the mc wrong and only answered one of the long answers and 2 of the short and got a 5 lol at like 70% lmao</p>

<p>That makes sense. It seems like they usually cover everything I think of in some way or another.
@thingschange. That’s what I’m mostly worried about with the free response, after I looked at the grading for some of them, especially number 8, I was thinking, how would I have thought of that. It’s a fossil, you can’t see cell structure or measure oxygen levels that exactly. It’s just a rock. If I had that on the test, I wouldn’t know what to do, and would just start writing things like recognize cell structure even though I would figure it’s wrong, as since you never know what they’re looking for, there’s a good chance that just writing something will give you some points.</p>

<p>@bmonticello23: so you need about a 70% to get a 5? just wondering, but how do you know?</p>

<p>last yr was 65/67 % this year shud b considerably lower…the cliffs book predicts 60+</p>

<p>lol barrons estimated 87%+ on MC</p>

<p>That link didn’t work 15saintmk</p>

<p>barrons is stupid dnt listen to them lol but i did get an 85% on the mc wait… lol but i had that and only answered the first frq and 2 short and passed a 5…</p>

<p>can someone with the cliffs pls explain to me how you did the gibbs free energy grid-in on practice test 1?</p>

<p>how many multiple choice questions do i have to get to get a 5 on ap bio exam?</p>

<p>sorry about that link, ill take it off</p>

<p>Tomorrow, my friends, we make history. Tomorrow, we set the standard - we set the curve, and we shall make our mark.</p>

<p>Whether or not you walk into the room ready or not, whether or not you know you will make a 5 - remember this, comrades - on that fateful day we will make our mark!</p>

<p>For our lives have not amounted to a number from 1-5 on a piece of paper, or an arbitrary determination of who “passes” and who “fails” - we have not worked this hard, all year long, to fail our upcoming challenge!</p>

<p>Fellow comrades, this is our calling. Tomorrow, we will all march into our rooms. Tomorrow, we will tell that exam who is the boss. AND tomorrow, my friends, is the day that we shall, against all odds, rise up against the evil monster that has dominated our life up to today and defeat it with a flaming sword! (pencil)</p>

<p>tl;dr I found this review helpful [AP</a> Bio - Final Review - YouTube](<a href=“AP Bio - Final Review - YouTube”>AP Bio - Final Review - YouTube)</p>

<p>@Tusing …pen, not pencil
And I found the REA book useful to read the section on labs and essay writing. It’s answering a lot of our questions, even though it still has the old format. Someone posted a link to it a while back, if you can’t find it, I’ll upload it to drive and post it.</p>
