I finally got impatient enough to just pay the $8 and make the phone call.
I got a 5 on both the Calculus BC exam and the AB subsection of the test, which gives me 8 units of credit.
At Berkeley it's like $3200 in tuition and fees for a 16 unit semester, so that saves me about $1600 from a $90 test. I'd say that's a nice return.
