Re: Chemistry OCR AS F321 Atoms, Bonds and Groups May 2012Maybe 55 for full UMS. I think 49 would be 83-85 UMS. That's what I think anyway. How do you think you did?(Original post by otrivine)
and if you get like 54 to 57 marks is that full UMS? and 49 what UMS you reckon -

Re: Chemistry OCR AS F321 Atoms, Bonds and Groups May 2012I thought it was the easiest paper I've ever done. After getting a B (1 mark of an A) in January. I'm definitely sure I got an A.(Original post by otrivine)

Re: Chemistry OCR AS F321 Atoms, Bonds and Groups May 2012yes true(Original post by Sarabande)
No reason not to. I don't see OCR as being such huge dickheads that they'll refuse to give you the mark for not mentioning the number of electrons.
thanks
