UMS question (A*)

[dragon_knight]

hi guys, i would like to ask how do i calculate UMS marks?

like for example, edexcel 2011 Jan Chemistry paper5 (out of 90):
A* 72
A   65
B   58
C   51
D   44
E   38
N   32

if i get 75 raw marks, what UMS do i get? how about if i get 80 raw marks?

because i saw on student room, that "you don't need to get full marks of the raw paper marks to get full UMS" i was just curious on that.

(and that's just a random figure, i know not many ppl get that but i'll set those as my target :] )

still no one? really no one knows how to calculate UMS above A*?

they have a very complicated series of statastical formulas to convert raw marks to ums

Lol......thats wat we're supposed to think!!

hmm i think its like this not sure thaugh , just assuming !!

If the mean is lets say 57 & they might add the standed diviation into it ! , & then they might devide the raw mark by  the standerd + the mean , so this way its possible for the UMS to be above 100 ! , in exceptional cases where the candidates scores really well!
not sure @ all about this just guessing

awww... that means you won't know your UMS marks even u had calculated your raw marks while doing past papers? not even when the grade boundaries are issued?

anyway... thanks n +rep~

i think i know

for example , the minimum raw mark to get grade A (80% UMS) is 29 out of 40
then if u score 34, for example then

u cn get ur approx. UMS simple by cross mltipilcation that is

ur UMS = 34*80/29

i thaught we were discussing about hw we get the  80 % , when the marks are 29/40  ?? rite ?

[Aadeez || Zafar]

No let me make it clear


29 in the minimum mark to get A out of 40

and 80% UMS is mimimun Percent to get A grade

there fore,   80% = 29
now u get 34 marks the
UMS for 34 would be = 34*80/29

yea thats looks allrite , but how do they say that  29/40 gives the 80% , thats my question

[Banana]

Dasith, yes thats true....29/40 does NOT give 80%....but Edexcel scale all the marks and fixa mark of 29/40 as the minimum to get 80% and hence get an A....this is basically to help improve our marks and make it comparable to previous papers.....good for us!!  

By the way....MY REP POWER IS 90 AND SO ARE MY POSTS!!

but it varies i think , specially in CIE , GCE -A/L
i dont knw about edexcel thaugh ! ,& i thaught we were discussing , how that variation occurs

29 out of 40 is just one exampleee


i solved a paper (40mark) and scored 30 and in the grading technique the mimnum marks to gain A grade was 29

i used the above method to calculate my rough UMS

You get A in that component. Add UMS of other and calculate for your subject.
