how did you find it bud?

I found it started off nice, but slowly went down hill. The last question was utter cr4p! I probably only got 1/2 marks on that part.

It was harder than june 14 defo, so I'm hoping low grade boundaries...A=53?

I found it pretty damn rough, only aiming to pass it really though! I used 10 as the pivot

You had to write how many to leave untouched too, should've been 17.5 unless you had to keep whole numbers of the acres then x=12 y=0 z=10 and untouched is 18 right ?

Sorry to hear about the shuttle sort, I'm sure the mixup won't count for much in the end though man :smile:
