Does anyone know the final grade boundaries for IB Math SL exam from 2011? Not the individual ones for the papers but the final ones that are out of 100

Your IB grade breaks down as follows: 20% Internal Assessment (IA-Project), 40% (Paper 1), and 40% (Paper 2).

Assuming the above poster is right, the overall 7 lower boundary is calculated as follows:
P1(80*(40/90)) + P2(77*(40/90)) + IA(34*(20/40)) = 35.56 + 34.22 + 17 = 86.78%
As of May 2011.

... damn, that's high.

not 100% sure but i roughly remember what they were:

54% was a 4 (roughly)
66% was a 5 (this I am sure about)
72% was a 6 (roughly)
80% was a 7 (rougly)

sorry I can check later but now I got to focus on History
