Any truth to the 79%+ for a 5 rumor?
Ifmclaughlinm34 if you got 40% on frq you probably got a 3-4 I guess. Would have to get a near perfect MC for a 5 with that frq score
@holycrayon Do you know this for a fact? Are they 10 random questions? Can anyone else verify this? Btw what do you need for a 5?
so lap49 on osmolarity of the cytosol?
Sorry , not 60%. I was referring to adding up points as I described
Yah so what r these experimental questions ? Never heard of this on any ap.??
I felt really good about the multiple choice but pretty bad about the FRQs. Based upon all of the AP Bio practice tests, you have to get around 77.5% on the whole thing to get a five (93/120) when you do all of their calculations.
hmm I don’t think it was supposed to be two groups, especially because one of the questions talked about how the bacteria had a preference for one of the nutrients. I am saying that at time 0, both nutrient 1 and 2 were availible for the bacteria to consumer. However, initially, only nutrient 1 decreased in concentration, while nutrient 2 stayed at a constant horizontal line, indicating it was not consumed. However, when nutrient 1 reached 0, that is when nutrient 2 began to decline because it was the only option.
Guys it really all depends on the curve and how you did on BOTH sections
The graph wasn’t measuring the amount of the nutrients, though, it was measuring the amount of bacteria on the plates (that contained either one or both nutrients). That’s what I’m saying and is why I’m so confused by everybody’s answer.
lap49 causes increased water retention of the mussels to prevent dessication from high salinity water
@iwanttogetintocollege yeah the FRQ was pretty awful. I think I may have done decent on the two long essays, but I missed one FRQ, and the others were pretty tough so that’s my main concern with the test.
yes, it was measuring the amount of nutrients. i beleive on the right side of the graph, there was a seperate y axis indicating that the line of the nutrients was measuring concentration.
Does anyone know if this AP score calculator (http://www.apcalculator.com/calculator/biology.php) is reliable? The curve seems a little too lenient for a 5…
@iwanttogetintocollege Thats how they curve it? Taking Your MC score and multi by 0.725 and adding that to FRQ* 1.25? I thought each part II question had a different score value (the first two having a greater value).
exactly what i talked about, said that lap94 allows for more water to be reabsorbed, rather then secrected as urine, leading to urine that is more concentrated salts. i didnt know exactly how to answer effect on osmolarity, but rather exaplined the process
The dotted lines showed the nutrient concentrations, it was really hard to interpret since it was subtle
in 2013, you needed a 47/58 (10 mc and 1 grid in are thrown out) for the mc and 31/41 on frq. The new scale is not /120 but /100.
47/58x50+31/41x50 = 78.32. Thus, 2013’s cutoff was a 78 for a 5.
that website is outdated
You are correct. The long ones are 10 points while the shorter ones are less
If you got 50/69 correct and 29/40 FRQ points what would that score be approximately? High 4, borderline 5? etc
