did only phy1,2,3. after marking using the mark schemes, i think i'll get;
Unit 1: 52/60
Unit 2: 49/60
Unit 3 (astrophysics): 30/32
Unit 3 (practical): 35/48 - no mark scheme for this, just a rough guess.
i then took an average of the grade boundaries from all the past june papers since 04 and then put them into the UMS converter and used trial and error to see what UMS mark i'd get. it seems with those current marks i'll be heading for around 270-280/300....but then again i'm only using an average for the grade boundaries and the converter will obviously have a few bugs. don't want to get my hopes up too high and finally end up with a worse mark.
