@awkplatypus Yes, it would be. 38 * 1.25 is 47.5 while 48 * .725 is 34.8. Giving you 82.3 (A very strong 5)
@Ludkis 29+31.25= 60.25. I would say that would be a 4, and depending on the curve I’d give that a very outside chance at a 5.
@Ludkis I’d recommend taking it. Or read the MC answer reasons, at least. But do try the grid-ins. And read the answers to the FRQ. The barron’s is definitely harder, and asks for more info to be known by you than the AP
@motivatedjunior at this point of time, just take 1 or 2 practice tests and see how well you do. Review all the questions that you missed on the practice tests and refresh your memory on your weaknesses. Also, make sure you know chi-squared and hardy-Weinberg. They will definitely appear on the grid-in. For the FRQs, I suggest you either take the time today and write all eight FRQs like you would tomorrow for the exam and grade yourself on it. If you’re too lazy, sum up what you would write in your head and look at the answer key. I have already posted a site where you can access 2013 and 2014 practice tests. Good luck studying! I’m also taking it tomorrow c:

im just curious but are ur ap classes 1 year long … b/c my ap bio class was 1 semester during the freakin fall…
Mine was a year. The only semester AP course at my school is lang&comp, and then AP Econs.
But that sucks
@Asiandoctor Mine was a year. The only semester AP course in my school is AP Government and Economics. Anyway, how is that even possible to have a semester to cram all that much information in?
Can anybody mention 4 things that happen during an immune system response to an antigen or infection?
Is time an issue on the multiple choice?
Depends on what type of reader you are, for me it is a bit bc of the extensive reading and partly due to the fact that I’m a slow reader
On my final exam, I got a 45/69 on MC/Grid-in, and 28/41 on frq. My teacher said that’s a high 3 according to the scale. Is that accurate?
Humoral Response - B-cell makes antibodies and memory B cells to remember the specific antigen
Cell-mediated Response - T cells produce Killer and Helper T Cells to kill all infected cells and pathogens while also helping with future identification
Inflammatory Response - histamine released to signal inflammation response and white blood cells/other immune cells go to the area of infection to fight off the disease
And idk the fourth one
Should we know how to calculate standard deviation?
btw anyone know a safe range for getting a 4 on the updated exam? i need a 4 atleast for college credit at my uni next year 
@elyvine changes every year based on how well people do. Last year I believe they graded a 5 on a nasty curve at around 80%. However, they did make it easier to get 3’s and 4’s which would be beneficial for you .
thanks bro and @eveningswan it’s on the formula sheet
@Eveningswan You should probably know how to calculate standard deviation because that may appear as a grid-in question tomorrow.
@elyvine Don’t ho;d me to this, but get at least 55-60%
@EveningSwan Yes. But more importantly, know how to graph the bar and what it means (bigger = more variation) since there’s a higher chance that the exam’ll give you the value
Anyone interested in having a kik chat to ask any AP bio questions they are unsure of? I think it will be beneficial for us who are taking it easy the second half of today. let me know if you guys would want to and i’ll start one up its just an idea
@ludkis I’d be open to it
@moony1972 By bar do you mean the standard error of the mean graph?
