I've sat both the January 2011 and June 2010. This was about as easy as the June 2010 paper, so it was pretty average really. The January 2011 was baad. I'd say it wont be too far from 42/60 for an A
100% UMS anywhere between 50 and 53 marks out of 60 on the paper

I damn hope so! cos I messed up the bit on the active load of sucrose into the sieve plate tube(which I did mention) but I completely forget about the hydrolysis of ATP to give hydrogen ions(and ADP) and potential gradient.
Haha i didn't even know about the hydrolysis part! Well it's only really 4 marks as 1 of the 5 marks is spelling the words right. So if you made 4 points you'd be fine

Not sure that is how it works, isn't 100 % UMS points only for full marks?
After you pass the A boundary the mark pattern between boundaries end but im fairly sure you need to get full marks for all the points

Nope. It's usually the difference between the A and B boundary, doubled, then added onto the A boundary.

The A boundary averages around 43 for this exam, and it's usually 5 marks between each boundary, suggesting that 90/90UMS would require 53/60.

I hope that helps.

Wow i didn't know that. That is brilliant! Is this just with OCR? or does it happen across multiple exam boards?

Well if you look at most the Grade boundaries the papers out of 60 and out of 90 UMS. So technically it should be 1 mark = 1.5 UMS. But if you look at say the January 2011 an A (which is 90%) UMS is 42 marks in the paper giving 72 UMS. But 72/42=1.7 so it's actually 1.7 UMS for one mark. Making 90 UMS (which is 100% UMS, sorry it's confusing) a mark of 90/1.7=53 in the paper. So getting 53/60 would get you 100% UMS. Hope that makes sense

Across exam boards. Some exams, such as Maths, usually have 100/100UMS to 75/75 raw conversions as the grade boundaries are quite high.

I don't think that's how it works. If you look at AQA's UMS converter, the gradient of marks awarded at each boundary changes, but remains constant after the B boundary changes, suggesting my method is more reliable.

Oh dear, i have no clue But we both agree 53 raw marks would give 100% yeah?

to be honest i think it was an easy paper and I think a lot of people have probably done very well so boundary for an A would be around 45-48

You think? I can't see how it could move out of the 42-44 range though, I hope it doesn't!!

It depends, by my hypothesis you'd need 56/60 in January 09, but only 50/60 in January 10. You can't be sure until the grade boundaries are released.

I'd have to disagree. There were 10 marks on the spirometer and it's a incredibly small topic, so I'm predicting around 43/60 for an A. We'll have to wait and see in August who's right!
