Got Q1 out fully, got the first two parts of Q2 (didn't manage i or ii), got the first part of Q3, got about half of Q4 (couldn't find cos(phi)), got about three quarters of Q5 (differentiated the function in alpha but couldn't get the minimum, got Q6 out fully.
So marking quite harshly I'll say that's 17 + 6 + 4 + 8 + 10 + 17 = 62
Hoping this will be a 2, be pretty gutted if I end up 1 mark below or similar.
It's a shame because the 2010 paper was so easy... managed to get 4.75 solutions out on that one.
