I got confused with the second part of Q2. "Find the value of U₂₀" or something. Was looking for something more complicated before I finally realised that it must just mean by inspection.

The clue was in the fact it was only one mark - one mark questions usually involve no working out.

Yeah, The 1 mark was more than enough of a clue. One of my friends calculated from U1-U20 to get that mark..

how do they wrk out the mark out of a 100. say u get 66 out of the 75.

roughly what is this out of a hundred. is it simply 66 multiplied by 100/75. gives 87.??????????

the raw to UMS conversion is not linear

huh can u explain

He means that you can't just take one constant number and multiply the RAW by it to get an UMS mark.

For example, if you got 32/75 and thats 50 UMS, then it doesn't necessarily mean that 64/75 is 100 UMS.
