<p>hope i didnt make a silly mistake! :P</p>
<p>DEC 22 seems so far away… ugggh</p>
<p>For those who used Barrrons</p>
<p>Did it cover every question on the test?</p>
<p>ok ok the clam question:
how will water affect it?
some say it’s locomotion because clams
have feet…true or false?</p>
<p>Does anyone remember what they put for the bacteria on the beef, and what’s significant about a large amount of bacteria?</p>
<p>I put All 3 and that they can produce toxins which are dangerous to humans. I was going to put 1 and 3 (Internal organs and kitchen stuff since bacteria can travel in an open medium), but there was no option for 1 and 3, so I chose all 3.</p>
<p>what did you guys feel about your practice books? Which ones did you use and comments?</p>
<p>Collegebound - I studied with Campbell’s Biology textbook? And honestly? It covered absolutely all of what was on the test and more. It’s obviously not light reading, but if you’re serious about an 800, that’s the way to go.</p>
<p>^ haha yep… only… no time? :)</p>
<p>anyways… after the fire question pls! and … the clam question…</p>
<p>BLAH. is it possble to have like a -5 = 800 on biology? ever? </p>
<p>i hope the december curve is actually better than most others… imean, cuz the ppl who have ap bio fresh in their minds didnt finish it yet, and its pretty late for seniorz to be taking an sat bio anyways right? sooo the curve will be better cuz more ppl suck? :P</p>
<p>^ no you can take ap bio as a junior, faill lol</p>
<p>^ huh what do u mean. </p>
<p>the ppl would would have finished ap bio completely wouldnt have it fresh in their minds (cuz the last time they had everything together was AP exams, not in may)</p>
<p>the ppl who are taking ap bio NOW would only have half the stuff covered. </p>
<p>so … would december curve be better than most others?</p>
<p>Curves are predetermined and the test taking population has no impact whatsoever on it.</p>
<p>Should I argue about the fire question again? Blahhh.</p>
<p>After a fire, soil does NOT take a long time to grow back. With a fire, nutrients are directly transitioned back into the soil.
Lichen and Moss would NOT be a good answer, and lichen and moss take over when rock and such are exposed and there is no soil for more established plants to take over. Soil is already there. Unless some catastrophic event exposed massive amounts of rock, lichen and moss would not be involved.
Woody shurbs seems like a suitable answer, but “woody” makes this choice unsuiting. Woody plants are higher up on the process of biological succession, as are conifers and trees.
Grasses and small plants take over quickly after a fire. The soil has been cleared for new plants, some seeds in the soil have been cracked open because of the heat and can quickly germinate. There is also no brushweed in the way, and plants can take over.</p>
<p>Haven’t you ever seen some section near a highway after a control burn? I lived in the valley along costal mountains that were burned over every year. You CAN’T possibly think that the WHOLE mountain was covered in lichen and moss after a year! Woody plants and trees need much more than a year to grow and take over a plot of land.</p>
<p>…yes?</p>
<p>^^I’m hoping the december curve is a lot better.</p>
<p>A couple people in the AP Bio class at my school took it last month and got scores no higher than a 620.
I took AP Bio last year, and used an ap study book to refresh my memory, and it all came back really easily. I did very well on the AP test, and knew my stuff, so hopefully my above post isn’t a bunch of crap.</p>
<p>Hopefully there weren’t too many past AP Bio students taking the test… And I felt that if I was only half way through AP Bio this year and took the test, without some self-studying, you would not know enough. Cross your fingers for a good curve!</p>
<p>wait, u sure that the curve is pre-determined? o=</p>
<p>^ Curves are not at all predetermined. You can always get a certain raw score, but what that raw score translates to is reliant on the curve.</p>
<p>Then how else would an 800 be -1 and then -4 some other time? Thats not called pre-determined.</p>
<p>The reason curves vary from time to time is because the general difficulty level of each question is different (inherently, it is impossible for one test to have the exact same difficulty). The overall “curve” takes into account all the difficulty levels of the questions (which is assigned prior to the test). You cannot determine the curve after the test because that means that the test taking population would have a direct impact on the curve. Since the ability of the test taking population varies, the tests from various test dates would not be comparable.</p>
<p>So basically, if the test really was harder than other previously administered tests, the curve will still reflect that and be more generous. However, the method in determining how “hard” a test is has nothing to do with who takes it.</p>
<p>Just think about it this way. If the curve was actually determined by the test taking population, wouldn’t the mean that every single test would have to be scored first before a single test could get an actual score (because the curve wouldn’t be set until every single test was graded).</p>
<p>dang. then i hope this was a hard test. was it?</p>
<p>hey, what is the chance of -4 (which is in reality 75/80 as a raw score) as an 800?</p>
