I'd say slightly harder. Last Q was difficult (dropped 8 marks) and I found multi choice was slightly harder than usual.

19 was b???

I got D 

[megt]

Wasted soo much time on 19

Smallest value was at b=0, then because 0.2 is Pr(4), pr(-1) must be 0.8  (a+0.2=1)
this makes the mean 0.8 X -1 + 0.2 X 4 = 0
for highest value, a=0, so nothing will be by neg 1, then solve to find the value of b (not sure what is was) by saying all probablilities add to 1. Then solve to find the mean. I think I got 1 which gave me E

Didn't mind it  - only blind guess was Q19 of MC because I didn't have time to think about it enough.
Hoping for an A.

I got k = 5/4, not negative though.
Tough exam though, ended up not having enough time so I left 4 marks worth of stuff blank from the last question and guessed the last two multiple choice.
Pretty happy with it overall though.
