With most subjects they only fluctuate about 1 or 2 marks each year, so these should be a good guide. To note, though, mark boundaries to science subjects and maths often vary a lot from year to year. If you have newer boundaries, please post them here so they can be added to the list.

How come the pdf file with the may 2007 boundaries has no section for extended essays?

[Mr. Shiver]

Many of the May 2008 grade boundaries can be found here: http://www.sevenoaks.....ries 2008.pdf

Only grade boundaries used in Time Zone 2 are here for subjects with more than one version of the exam (such as Math SL/HL, Biology, and Physics).

Edited by Mr. Shiver, Aug 07, 2008 - 18:36.

[hamani]

When you say time zones you mean there are different papers for different area or that different zones are graded differently?

[cereja]

Different papers. So that way no one can get questions from the other side of the world.

[Mr. Shiver]

The grade boundaries are also determined separately for each IB time zone based on the different sets of exam papers.

is it true that IBO scales the marks based on how the whole world is doing?
wow..a 55% in english A1 overall is a 5...amazing, in Canada, a 5 in english means you can skip english 101

Of course - would it not be stupid that a Chinese candidate would need 70 points for a 7 and a Canadian would only need 65 points for a seven. It's the same test for everyone, so the scaling is based on the performance of the WHOLE world. However, different timezone tests (like in math) will have different grade boundaries, since the questions are different. This is why an American's paper 1 score of 85 points might be a seven and an Australian would get only a 6 for it.

I understand the whole Chinese person needing to get higher points for a 7 in Chinese language, but why does an Australian get a 6 while an American get a different score due to different time zones? I don't get it.

The November papers are easier for some reason. There are more people that take the ones in May, so they are harder. Grade boundaries are therefore higher for the November papers (though only slightly).

That's actually a good reason to do retakes, when you think of it

Edited by Vvi, Jan 02, 2009 - 22:16.

[deissi]

Even if it's the same session (i.e. the same May session), the Australian would have a different extract than the one that the American has for Eng A1 P1. Therefore, they also have separate mark boundaries.

[Hughie]

Wait.....how come there's no mark boundaries for Japanese B (SL)? Does anybody know where I can get the information for Jap?

Wait.....how come there's no mark boundaries for Japanese B (SL)? Does anybody know where I can get the information for Jap?

Jap B SL available in the Seven Oaks link.

I know that this is a bit of a strange request, but does anybody know where I can find the mark boundaries for May 2000 exams, particulary French B SL Paper One? We did this as a practise in class, and the teacher could not find the mark boundaries, so he used an alternate formula for assigning marks that marked us down on average about 1.5-2 points from what we should have gotten. If I can show him the mark boundaries, he may change them.

Thanks in advance for your help.

Does anyone have any Psychology HL Paper 3 mark boundaries?
