if the cut-off was around 55/70 for e4 in 2012, then it definitely wouldn't be 50/70 this year. This test wasn't much harder than the last years, except for the binomial.55/70 was the band 6 cut-off for 2012 which was really easy.
Most years when it was /84 had band 6 cut-offs of ~67%, which would be 47/70. But with the new format I'm predicting a 50/70 cut-off.
Though obviously this could be wrong.
i think the cutoff should be around 52-53.. not 50/70. That's pretty low. Just because of a few hard questions the cut-off isn't gonna change by 5 marks.
