@SAT4Breakfast No, obligate mutualism means both plants NEED each other to survive. The line will be stagnant for a short period until the plants eventually die and decompose. @latiere Unfortunately they use a specific rubric and theres only a certain amount of correct answers, so you most likely will not get any points unless you used a key indicator or something that the grader notices.
@APS2000 Thank you. Does that wreck my chances for a 4?
Depends on the rest of your test? How well did you do on the rest of frq?
anyone taking the alternate tomorrow with me? 
Does anyone know if and when we are allowed to discuss the grid-in questions?
Never.
For the second frq part b do you guys think that they would accept (10^2.5)/2 even though the most appropriate answer is probably (10^3)/2
@neehal120 I think so… Or at least I put the same thing + it’s close enough I think they might gah hopefully
What percentage right do you guys think need to get correct for a 5 on this years exam based the curve in previous years and it’s difficulty relative other to other years
Ughhh percentages are out and they seem to be about the same :(( praying lenient grading on the FRQs
If anyone didn’t see on Twitter, the score distributions are-
5: 6.3%, 4: 20.6%, 3: 33.6%, 2: 29.2%, 1: 10.3%
I really hope that frqs were lenient because that may be the difference between a four or five for me, even the difference between a three and five, I’m just gonna keep praying.
But from what Trevor packer said, it seems as if they traded the first six leniently and last two very harsh, so rip me
Hey anyone else notice whats weird about what Trevor said? “AP Biology grid-ins that require mathematical calculation: students performed quite poorly: more than 50% earned 0 or 1 pt out of 5.” There is 6 grid-ins, so one must have been dropped.
@Lebronjamesisbad, did u even take the exam. The last 2 were hella easy but hella ppl prolly overwrote for questions 1 and 2
And ran out of time, so it’s not a matter of gradin. Hard but rather time management
@upsidedown2 yeah they always throw out 1 grid in and 10 out of the 63 nongrid in because they were experimental
The fact that 6.3% of people get a 5 worries me. I thought I did pretty well but now I’m not too sure.
@vivigsk1 ok lol, that makes sense I knew the last two questions weren’t that bad, so I thought that my answers were too basic if 50 percent and 66 percent of peopl got that wrong
Any ideas on why http://www.totalregistration.net/AP-Exam-Registration-Service/2016-AP-Exam-Score-Distributions.php states that “Good predictor of whether you scored high on this year’s AP Bio exam is how well you did on Q4 (gene expression)” How would one question make such predictions? lol
