I got the exact same exam and I agree with you a 100%. I was shocked with Part A and B. The wording was confusing and much harder than old past papers and the specimen exam made me think it would be.
The Ted singer question was pretty hard. I had studied performance analysis, ratios, variances, even the demand equation with logs and everything else …all that hard stuff!! When I saw they were talking about EV and profit it kinda threw me off the track a bit so I will be resitting the exam for sure Hope you get 50% though 🙂
