GOOD QUESTION RE 10 'POOR PERFORMERS'
A question that I often hear Chris & it's worth explaining in detail.
There are two main points on the removal of the 10 MCQs (scored out of 140 rather than 150).
1. The 10 removed are those that 'performed least well' against the standard criteria used at the marking stage (not simply the hardest MCQs). One factor is difficulty (how many candidates got the MCQ wrong), but the evaluation also looks at whether the MCQ was fair, performed as expected, and provided a valid test of the syllabus. Extreme cases (where almost everyone got the MCQ wrong) get removed, as do MCQs that show poor discrimination or other flaws. Because these are the poorest-performing MCQs, the large majority of candidates got them wrong. Removing them therefore raises most people’s percentage on the remaining 140 and makes a pass more likely. The chance that a candidate who was struggling on the better-performing MCQs somehow answered a high proportion of these 10 correctly is remote — which is why the process is designed not to unfairly penalise candidates and why it works in favour of the vast majority.
2. The pass mark is 65% (91/140 for the INSP exam; 55%, 77/140 for the SGT exam). If the 10 poor performers were included and the same percentage applied, candidates would need 98/150 (83/150 in the SGT exam). Adding those poorer-performing MCQs does not make the exam easier in percentage terms; for the typical candidate it would require getting a higher proportion of a harder MCQs correct to hit 65%/55%. The College removes them precisely so the exam remains valid and does not unfairly penalise people for MCQs that did not perform acceptably.
I hope that explains the situation and allays your understandable concerns?

Paul, one thing that really concerns me and some friends is why they remove 10 questions? What is the reason for this as surely it causes a fairness issue if you would've passed prior to the removal?

FALSE IMPRISONMENT & KIDNAP
Brief summaries of the offences - but please read Blackstone's as the Keynotes contain some really juicy case law (case law in the Keynotes = MCQ scenarios).
No excuses.
They are covered in just over 1.5 pages of A4.
