Examiner guedline is not reliable

As we know the examiner gudline it’s writen by their should be examined specefic MTQ but it’s true that as it hapened with me.
Ifailed f2with 44 last January in 2017 , the examiner they have given two MTQ not related part ( c , d and e) , like the question was : 1. Revenue return on single ticket.
2. The cost of training operating staff per return journy ( Driver and firemna)
3.The cost of catering staff per erturn journey.
4.Average fixed production cost.
These question iyhink they related service costing but why they have given these MTQ.
Is there any cahnge MTQ program in 2017.
Thank you.
