# IB 2009 Grade Boundaries? watch

1. (Original post by Rainfaery)
Calculating the percentages, the overall grade for a 7 should be 74%, if you use the weighting. 1% isn't that much, but it can be a huge difference if you're right on the edge.
well you calculated it wrong. If the information for the boundaries for Maths HL Series TZ1 is correct the percentage is as follows:
75/120 x 0.3 + 91/120 x 0.3 + 48/60 x 0.2 + 35/40 x 0.2 = exactly 75%.

My calculator skills are clearly decaying quickly.

75/120 for paper 1?! Bhahahahahahahah. That just made my day. ******* IB, setting that paper.

Although I agree, with the boundary for a 7 so low for paper 1, I can't believe that a 75% overall is a 7. Ah well.
Although they made paper 1 low...they balanced it out with a high paper 2 boundary. I still think 75 is a bit high comparing the overall difficulty to last year

it's a good thing
5. Hey, alas it appears that at sevenoaks they have nobody doing Psychology HL nor Computer Science HL, so I don;t actually know the garde boundaries

Anybody got the details?

in Sevenoak's website.
I can't believe my eyes, 73% for a 7 in Math HL and (i believe) a record low of 77/120 for a 7 in paper 2
Well, it was supposed to be a monster. I can breathe a deep sigh of relief about next year...

usually psychology HL and SL boundaries are about the same, expect HL to be 1% higher than SL, which is around 69% to get a 7.
8. Does anybody know the grade boundaries for ITGS SL?
9. where is grade boundary for HL Math Series TZ2?

well as i said it doesnt cover all subjects for the six groups. This means that the subject is not provided in Sevenoaks. So if you want the grade boundary i think you need to contact ur IBC.

Use the Grade Boudaries for P1 and P2 from sevenoaks...and the Grade Boundaries I posted for Paper 3 above because both timezones (TZ0) had the same paper 3 for series.
