For UMS:

90% = A*
80% = A
70% = B

and so on... always.
I'm aware but the actual UMS score changes depending on different grade boundaries & raw marks.

To get a B overall = 210 UMS
210-127= 83 UMS required on this paper for him to get a B overall.

84/120 =70% therefore this is a B grade. Regardless of raw marks.
I am speaking just of UMS.
He asked 'if I get a C on this paper will I get a B overall'- the answer is yes as he could get 83/120 (69.1%) which would be a C grade, on this paper, and still get a B overall.

I really want to get a B in maths overall, but if I get a C on this paper, will I still manage to scrape a B, do you think? I have 127 "points" overall, a B for Unit 1 and a B for Unit 2.

To get a B overall you need 83/120 marks on this paper. 84/120 marks is the lowest B you can get, so if you were to get a C on this paper it is unlikely you would get a B overall. If you get a B or higher on this paper you will definitely get a B overall

So, if I get a (really) high C, I could still get a B overall? (Sorry, I don't quite understand the UMS points part!)

I'm pretty sure I could get a B on this...the more I think about the exam, the more it worries me hahah :') I presume it would need to be only a couple of marks off of a B to still get the overall B?

Sorry for all the questions! Also, I'm a "she" :P

Sorry for the gender mixup!

Basically, yes, it is possible for you to get a C on this and end up with a B overall. I can't tell you how many marks as I don't know how the raw marks/ UMS correlates, but I would probably guess you can only be either 1 or 2 marks below a B. If you get a B or higher on this then you will guaranteed get a B overall

To make things fair regardless of the difficulty of the paper, exam boards convert your raw marks into a 'UMS' mark. This means that someone taking a really hard test may only get 50/80 marks, whereas someone the following year may take an easy test and end up with 60/80 marks. If everyone sitting it finds it 'generally' easy, the raw marks to UMS conversion will be lowered. This means that both people would receive 100/120 UMS, for example.

The actual paper is out of 80 total raw marks.
This test has a total maximum possible UMS of 120.
Depending on how hard the paper was found by students, raw marks will be converted to UMS.
These grade boundaries are not released until day before results day, but on TSR there have been a few suggestions of possible grade boundaries...

66/80 - 108/120 (A*)
52/80 - 96/120 (A)
41/80 - 84/120 (B)
33/80 - 72/120 (C)

As I said before, you need 83/120 (or more) on this paper to get a B overall.
84/120 UMS marks is a B grade, meaning that 83/120 is the highest mark for a C grade. So, if you get a very high C grade it is possible for a B overall.

Oh, I see! Teachers talk about grade boundaries being higher or lower

I did count through my paper once I'd finished what I could, and marked myself on what I could get (I know it's not accurate, of course!), or taking away marks/partial marks for questions I didn't answer or understand, and I remember giving myself 40-43/80. Of course it will probably be different when marked by the board, it's just a habit of mine.

Hopefully it'll be enough. Thankyou for your help!

Hello, i would like to you to see if these could be correct.
Question 1: (x and y perimeter)
2x=5y

2:2x+2y = perimeter

3:total perimeter as x and y =14x because of subsitution. i multiplied all sides by 5, subsituted in 2x for 5y and added them together 5x+5x+2x+2x=14x
if you can check this i would be grateful
