Question about grading scale

[The Breeze]

Does anybody know what the range of raw scores that converts into their corresponding points on the 5 point scale? Specifically for APUSH, english language, and statistics. i'm set for bio

according to a princeton review book for AP Bio i returned to my library recently...
120 M/C x .75 points for each = 90 max for M/C
4 essays x 10 points each x 1.5 multiplier = 60 max for essays
that totals to a max of 150 points on the AP Bio exam
i don't have the book with me, but it was something like:
102 (or so) - 150 = 5
82 - 101 = 4
60 - 81 = 3
40 - 59 = 2
1 - 39 = 1
(that seems like a huge range for a 5)
i think something like this would be so helpful, because now i can look at it like "ok i'm positive i won't miss more than 10 or so on the M/C, so i only have to average four 4-quality essays to get a 5"
i do find it odd that i can't seem to find this information anywhere, so if anyone is willing to share, please do so?

I'm pretty sure the grading curve changes yearly. However, if you go to the collegeboard site you can see the trend between the raw scores and the final scores - they don't tend to vary extremely so you'll have a loose guideline. It's also different from subject to subject, so don't expect the grading scale for AP Human Geography to be the same as AP Calculus BC.

http://www.collegeboard.com/student/testing/ap/exgrd_set.html has a table for AP US and English language from a while ago, but it doesn't look like it changes too much from year to year. i don't know if this helps?
