*** Official AP Biology Thread 2012-2013 ***

<p>to make some people feel better everyone at my school failed it so that adds afew people to the pool of 2s and 1s hahaha</p>

<p>Same thing happened to me lol. Realized it in the last 5 mins and just shat words trying to get some points.</p>

<p>My entire class was caught off guard by the test. We knew that it was a different format but we weren’t expecting such a drastic change. There was no factual recall at all and nothing that I studied was on the test besides for one question on chemiosmosis and I think there was another straight bio question. Everything else was graphs and tables. I actually felt like I was taking an environmental science exam. In that way, it was actually difficult. </p>

<p>Half my class also stopped after the bubbling in because apparently it said “STOP” at the bottom of the page. They didn’t get to the grid ins. Thankfully I did but time was called when I was bubbling in my second answer. Overall it was rough.</p>

<p>Is a 5 still possible if you didn’t answer the grid-ins?xD</p>

<p>GUYS I didnt have enough time to do 2 FRQs!!! Am i still able to achieve a 5??</p>

<p>Finished all my essays though and I think I got a full points on more than half. The curve this year is most likely going to be in our favor because I doubt tons of people did extremely well</p>

<p>Ap stat had 6 frq so I thought ap bio had 6 I even check to see what the lady page was but it was just a bunch if stat crap so I was like o there’s nothing</p>

<p>my teacher never even showed us a practice exam and I actually think I was better off because I didn’t have any prior expectations about the test… did a lot of people really not finish the questions? all I need is a four and I feel pretty confident about this curve</p>

<p>Some kid next to me took a nap and then the proctor came and asked if he was okay and the kid was like yeah I just had a seizure so now in resting HAHA bulli*****</p>

<p>Guys, you were supposed to get a really large Chi-square test statistic and reject the null. I don’t know what stupidity got into your heads. Crappy public school problems, I guess.</p>

<p>Not getting into specificss but the instructions said u cannot write in outline form only paragraph… Does this mean i couldnt write it out like
a)(answer using full sentences)
B (answer using full sentences)
C (answer using full sentences) and so on?</p>

<p>I was a little worried while doing the frq thanks!</p>

<p>I barely had any time to do the grid-ins :frowning: I think I filled in 3 and got 1 of them right… And did anybody else totally lose focus during the last couple of multiple choice? I just couldn’t get myself to follow some of the passages. The FRQs were initially daunting during the reading period but once I actually got to them I managed to pull some things out of the hat. Crossing my fingers for a generous curve!</p>

<p>As long as you wrote in complete sentences you’re fine! They actually prefer you to break your answer up like a, b, c…!</p>

<p>I agree with alliekinz
the hard part was figuring out the expected scores
different expected score =different chi statistics= some people rejecting and some people not rejecting</p>

<p>For the null hypothesis equation, you’re not going to expect that the values be 60,0,0. The null hypothesis is the control, the status quo. We are trying to prove that the flies will move towards the banana and will produce values such as 60,0 and 0. What some of you are saying is the null hypothesis should in fact be the alternative hypothesis. The null hypothesis would predict that the distributions would be even. Stats AP ftw.</p>

<p>And yeah someone else asked this too but was one of the grid-ins 100%?</p>

<p>That’s what I got for the first.</p>

<p>yeah exactly but is it 20,20,20 or 30,0,30?</p>

<p>I said it would remain a 21, 18, 21, in a 7:6:7 ratio. That made it hella easy to reject and explain why.xD</p>

<p>I put down 20, 20, 20. I think you can have either though… #apbio5</p>
