boundary for 120ums guys?

I think on the whole, it was an okay-slightly hard paper

section A was slightly harder than usual IMO

Lower than normal, I think. Section A was a bit harder than normal, and loads of people would have got 1c or the peak emf one. QWC question was pretty straightforward though, so that might balance it out.

I put 8F ( If i'm thinking of the right question) and I also guessed the Mars one, but I think I should have put 25MJ
