Practise multiple-choice questions

 

This appendix contains two pairs of two sample question papers in the standard City & Guilds multiple-choice style, as four pages. These sample items illustrate the kind of question to be expected in the examination. They are closely representative of the scope of the examination, but not exactly so as they were not originated by City and Guilds of London Institute.

Unlike the modern single 80 question RAE exam, these are split into the older examination format of two separate papers of the two exams taken at the same sitting. The first paper in each pair contains 45 questions and the second one 55 questions. You should allow yourself respectively 75 minutes for the 45 questions for paper 1, and 90 minutes for the 55 questions in paper 2. There was usually a break of 15 minutes between parts 1 and 2. The use of a basic (non-scientific) calculator and a copy of document BR(68) is allowed during the exam.

Despite the older format of two separate exam papers instead of the modern single paper exam, we hope you find these sample questions to be of use to you.
