***AP Biology 2015 Thread***

You’ll pass.

I’m not sure of the exact curve. 75%+ is for a 5. At least 45% is probably a pass – when looking at other AP exams

Because this exam is fairly new, we don’t have a good estimate. As well, the college board determines the curve based on how well people do

How many human systems are covered in AP Biology? I can only remember covering nervous system, immune system, and endocrine system.

What do you guys think some of the FRQ’s are gonna be? I know the majority of the endocrine system with what the posterior pituitary and anterior pituitary releases, but other than that I don’t know what to study. I should also add that I know most of the hormones with insulin and glucagon. However, i don’t know much about plants at all

Does anyone know how to do question 121 (the hardy weinberg one) on the 2014 AP Bio practice exam. I keep getting half of the right answer.

@HankGreen Those are the three you need to know best

@FlowerChild3525 Thank you!

Anyone have any pun net square practice with answers with fruit flies. That is my weakest.

@Ludkis Draw yourself some.

Vestigal (rr) x Wild Type (Rr)

You should get:
50% Rr
50% rr

How should I review the labs? Will I need to know specifics from them or just enough background information to be able to apply what I learned from them?

@moony1972 Thanks!

Bozeman Science and CrashCourse are great for last minute AP Biology review over weak subjects.

@rpanther Background info to apply what you learned

so how many MC’s is it officially, 53 or 69?

My biggest problem is the multiple choice. I have been missing around 18-20, and want to cut it down to 12-15. Anyone have any tips. Really trying to get a 4.

Also, if you want, you can try getAFive.com
The videos for ap bio are short (like 5 minutes) but he gives you an idea of what’s important for the ap exam

@RoadtotheIvies98 Should be 63 + 6

@Ludkis 18-20 wrong on MC + Grid-Ins plus 75% on FRQs is a 5…

Thanks for the helpful posts and resources!
Best of luck to all of you tomorrow! You will do great!

@ultimate314 Always find q first because you are not sure if the dominant population are heterozygous or not. So you take 1759/(11088+1759) and you get 0.14. That is your q-squared value (it’s the percentage of recessive). Then square root it and you get 0.37. That is you q value. From the formula, (p+q=1), p is 1-0.37 or 0.63. Then to find heterozygous, you calculate 2pq and in this case, 2(0.63)(0.37) which is 0.47<- your answer.

@Ludkis Focus on the info given in the question. Most of the time, the answer should be fairly obvious just from the question. Brush up on any CONCEPTS that you seem to be missing a lot of. Also, check if any of the answers have one word in it that makes it incorrect. What I did was that I wrote whether each answer statement was true or false, then I read the question.
