I have a question! What is the curve like for ap calc? I know it varies every yeear, but approximately, how much % gives you a 5?
I think the max raw score is 108, so wuts the cut off for a 5? Thanks!~~~

In '98 it was 65.
With the silent... and the open... and the... yeah.

My calc teacher probably lied to us:
84 - 108 = 5
~64 - 83 = 4
I don't know any lower because I've only scored 5s based on his scale using his hard@$$ tests.
Here's how you do it using the college board tables.
Go there, scroll to page 8.
Go to Percent at AP5 for 2001. I'm sure the College Board uses the scores from more than just 1 yr, but here's just for simplicty's sake...
38.8% of the nation gets 5's. You take that number and you subtact it from 50%.
0.5 - 0.388 = 0.112.
Consult a normal distribution table:
Now 0.112 falls at around 0.31 on the table.
Scroll to page 9 on the College Board guide, and find the Composite Std. Deviation.
Take that and multiply by wat u got on the table.
22.98 * 0.31 = 7.1238
Now on the College Board guide look at the COMPOSITE MEAN. That's 53.4. Add the mean to what you got above....
You get: 60.5238. Lets say 61 gets you a 5. I say close enough to 65. I'd go with 65 though. In fact, I'm so pessimistic I would go with the 84 figure our calc teacher gave us =]. Maybe thats why our teacher gets a 75% 5 rate, and a 97% passing rate.

BTW I just did those calculations above, except I averaged the table's values.
For example, instead of taking 2001's std deviation for composite, I averaged it for the 5 years.
I worked it out and the 5 cutoff should be 62.9. Lets make that 63...

Does anyone know what the "curve" was for the 1998 Calc AB test?
How many points give u a 5?

Ha...not only does our teacher have a 100% passing rate, the entire SCHOOL does!

75-108 is a five.
So you can get like 38 on both sections and get a very low five - hey but still a five

What year is that Aawesome? I think they redo it every year. I know in '98 it was 65/108.
