Why there are no ‘real’ MSRA past papers
And why these are the next best thing.
There exists a confidential bank of questions which are used to construct MSRA papers. Every year a handful of new questions are added to it, if they have passed piloting.
Official past papers are not released as this would remove a substantial amount of questions from this bank which could not be reused.
This is also why NHS England are hesitant to release more practice papers. MSRA SJT questions are expensive to produce, and undergo a rigorous validation cycle before they are included in the official bank.
Some third-party question banks claim to offer past papers. This normally consists of questions that have been gleaned from applicants recalling their recent sitting. We believe that without an official answer key this practice material lacks value, as the "correct" answer is the best guess of a third-party exam writer, not that of the official exam. What you'd actually be practicing is to model the judgement of that third-party exam writer.
In fact, we believe that all third-party MSRA SJT practice material lacks value for the same reason and is likely to worsen performance, as you learn the habits and judgement of the third-party writer, not of the official MSRA exam writers.
This is why we have set about to make the only fully validated MSRA SJT question bank. By using robust statistical methods of validation and mimicing the WPG's own SJT development process, we can ensure our questions are consistent with the official exam.
