# How does CIE calculate grades? by adding marks or taking percentage? watch

1. Hey, I have some questions about how CIE calculate marks. Take example of chemistry,According to syllabus, 5 papers each weight 15%, 23%, 12%,38% and 12%. So when we calculate our total mark, we use what we got in each paper divided by the total mark of that paper then times its percentage and add all of them together. However, according to gt shows on xtremepapers.com, they only say get about 185 out of 260 for these five papers will lead an A*, they don't even mention the percentage. So how does CIE work actually? Do they just add marks together?
Thx for any help.

As with all of these public exams use a UMS conversion to determine the grade.
To achieve an A* requires a certain amount of UMS, other requirements may also exist.

Where can I find my UMS?

The result statement only gives the overall percentage, out of 100.

This will be percentage UMS

So our grade is related to the UMS rather than the adding marks? I hate CIE

The marks you get on each paper dictate what UMS you get for those papers (look up grade boundaries). A certain number of UMS always means the same grade but the number of marks on specific papers can differ due to the possibility that different papers turn out to be harder or easier than others. Ie. you could get 60/75 in a 2009 paper and get 80 UMS out of 100, but then in the 2011 paper it only takes 50/75 to get 80 UMS because the paper was unusually tricky for everyone that sat it.

Edit: This has nothing to do with CIE. This is how it works on all exam boards.

CIE says get about 65 out of 100 in 2012' summer paper 4 will be A, does this mean if I get 65, my UMS will be 80 for paper 4? But look at last year's students resylt in my school, there were not many As, why they failed to get just 65 marks?

If you don't know what the paper was like, why wonder why they failed to get 65 out of 100 in it? Papers vary in difficulty. Getting 50 on one paper could be harder than getting 70 on another (though they try very hard not to let it vary that much). I said this in my last post.
