A quick update on this, thanks to Phil I have now found all of the questions from the OPS exam in the document that he linked to earlier in the thread. Unfortunately for myself and others on my course this document was only mentioned once at the very beginning of our OPS book. We had not been told by our training provider to pay attention to it and so focussed on studying our material.
Also I would like to mention that I do not study the question bank but rather read through the material multiple times eventually summarising it into study notes then focussing on those. The exam has taken a different direction and without being told to change your focus then it would be next to impossible to get a pass mark.
I am all in favour of making exams more difficult and weeding out those who rely solely on question banks however students need to be directed to the correct material in order to prepare themselves for an exam.
