A2 OCR Chemistry Raw Marks To UMS Tables

hey, just wondering, does anyone have/know the raw marks to UMS tables for the last year and the past couple of years' A2 Chemistry OCR exams? If so please post it up here, thanks alot :biggrin: . If you have a set of mark schemes ordered from OCR Chemistry, then the "Raw Marks to UMS" assessment table should be on the second page.

I know Chains Rings and Spectroscopy in January 2004 was 70/90 raw marks to get an A - 80 UMS

Edit: I want to know this info. coz I marked some of my own past papers and want to know what UMS points I would've got.

Are you absolutely 100% sure that 70/90 raw marks was an A for the chains and rings paper in jan 04? The raw mark i got on the paper was 73/90 but my UMS mark turned out to be 67. I thought it might have been dodgey marking or something at the time so i asked for the script from the exam board. After checking through it with my teacher and the markscheme we found no errors in marking so i was advised not to have it remarked.
If the figures u have for the raw mark conversion is accurate, does that mean i was denied the grade i deserved? :frown: Man i knew i shudda sent the paper back to check for admin errors at least. If this costs me a place at uni .......... *sighs
Nothing i can do now, can't get it remarked since its past 2-3 week window after the results.

It was not. 70 raw marks was 63 UMS - I know this because that's what I scored. It was the baseline B. (Retook this, of course)

yea, it seems some arseholes did really well on that exam and pushed the grade boundaries right down. I thought i'd done really well on the exam (not 100%, but high 90s) and yet i was pushed way down to the grade boundary!
I got 79 for Chains Rings and Spec. Does that mean I actually got 86Raw?? Because if so, it's really unfair that I didn't recieve 86UMS! I've never known of UMS marks being lower than Raw marks. Crikey!

my chemistry teacher told me that when we were going over that paper (and he usually knows his stuff quite well) but nobody in my skool actually sat it though so i'll let u be the judge of the accuracy. Although u guys have sat it so should know the grade better than my teacher probably.

70 raw marks for 63 UMS sounds a bit unfair?????

for ocr salters exam i took in jan, I got 62 raw, this was pushed down to 54 UMS!! i was livid to say the least.

Crap, they'd better not do that with last weeks synpotic paper or I'm so screwed.

how do u all know yer raw marks anyway? did u all request yer papers back? I personally found Chains and Rings and Spec this year not too hard and some people found it really easy, so it looks like that papers grade boundaries are gonna f**kin go up big time!!! They should make a limit to how far they go, such as 85% is a guaranteed 80UMS no matter how many people get 90%.

I just asked my friend on MSN today, and she says that she also remembers the teacher saying 70/90 raw marks to get an A - 80 UMS in Jan 2004's paper, but then she said "I think the teacher probably just did a brief estimate or probably got mixed up with June 2003"

oh yeah peeps, how did u find Chemistry Unifying Concepts and Chains and Rings overall?

I thought ChainsRingsSpec was not too bad but definitely not "easy" or "really easy" as some of my modest/foolish friends propose.

Unifying Concepts was alrite a few tricky questions, but luckily I do maths. Those in my chemistry group who dont do maths thought it was a bit of a painful paper. Looks as if Mathematicians get the benefit for this paper (probably the same for the past couple of unifying concepts exams, as I've done past papers and they are also quite "mathematically" conceptualised). Another lucky thing is that not everyone do Maths and Chemistry combination at A2 level, so the UMS will probably be quite fair.

Ive got Biochemistry on Tuesday and I personally find there's quite alot to learn and it'll be a challenge to get a decent grade since almost everyone takes chemistry and biology combo (yeah, I do both but unfortunately im crap at biochem!!). It only takes a handful of amazing grades to screw up the UMS!

Well, in my college my teacher actually telephoned the OCR exam board and talked to them about the grading in Januraray, there were people in my class who got a UMS equivalent to 70%, a B ended up with a D. This was found out because one was one mark from a C and wanted to see their paper and they actualy had 75% which should be a B almost an A, so what my teacher found out was that they based the UMS score and grade on past experience, funny thing was that I was the odd one from everyone. Last year in my AS I scraped a C and ended up with an A and UMS 75 whereas a girl in my class with a reasonabely high A in AS got a UMS 1 less than for an A. So my teacher figured I stormed the exam which I thought I had and she had messed it up very badly, but putting past experience into it - its all dependant on past results for some stupid reason. Sop basically its all that crap OCR were doing a few years ago to A-Levels. But, he found out to balance it up the Foundation Chemistry results are marked up in AS.

soz, I think im not the only one confused, but what do u actually mean by past experience?

yer serious? omg that's so wrong. So how does it work? If u do well in the previous modules but do crap in this module then and vice versa???

oh and is this from what u know, for OCR only?

To be honest I dunno how they work it out but if you did mint in loads of other modules and failed Chains, rings and spec then u should be getting a UMS higher than what u really did get. But, they sed it balances up with foundation chemistry. Really, its all that crap from 2 years ago again where it was impossible to get an A and stuff i think they marked ur coursework down that year

what are raw marks and ums marks?


Raw marks are the number of marks u get in the paper and from my findings UMS are the marks you are actually awarded that are then used to findur grade.

Yes I did request the paper back, as the mark was uncharacteristically low, which is how I know my raw mark.
