Last June that would've been ~95 UMS, in the January 2011 exam it would've been 105 UMS. I think the grade boundaries for this exam won't be as high as June 2010 but similar to Jan 2011.

Yeah Magic Wang, was ridiculous... I don't think I saw you in the exam hall which is peculiar seeing as our second names both begin with B.

I didn't see you in the hall either :s-smilie: I saw you afterwards but I was talking to someone else so I didn't get a chance to say hi.

Mm i rarely have time to check, im very thorough the first tie round, i find it hard to leave questions uncomplete so ill only tend to move on when im sure its right. I remembered pKa and strength via buffer solutions, when acid and salt are same conc pH=pKa and so lower pKas mean lower pH means more acidy means stronger acid



i know what your talking about, thats only when the ration of acid to conjugate base is 1:1 that pka=ph, they never said it was...
