Multiple Choice questions can be a useful resource for revision, this collection is for A Level mathematics.
I have often mentioned Gareth Westwater’s site, Westie’s Workshop, recent additions include compilations of AQA multiple choice questions, we have Pure, Statistics, and Mechanics.



A source of multiple choice A Level questions, particularly for Pure Mathematics is Diagnostic Questions; see for example this quiz I created on Logarithms and Exponentials.

The UK Maths Challenges provide a wonderful library of multiple choice problems; you can practice for the UK Maths Challenges including the past papers for the Senior Challenges. Questions and full solutions are provided.
As well as a full solution that does not use the multiple-choice answers further ideas are given for investigation.

Digging into the archives….

A trip down memory lane! (Edexcel’s Emporium has some papers from this era.)
University of London June 1986 Mathematics 1
At the start of my teaching career, I really liked the first paper of the Mathematics A level from the University of London School Examinations Board – thirty multiple choice questions to complete in one hour, 15 minutes.

For questions 1 to 20, candidates had to select one answer from 5 and for questions 21-30 the instructions were as follows.
University of London June 1986 Mathematics 1
The pdf file here has the paper, followed by the exam board answers followed by notes from the 1986 version of me! These days I would illustrate with Desmos and/or WolframAlpha for example as well where appropriate.
Note the comment from Graham Cummings below, there are further papers available in Edexcel’s Emporium:
The Emporium has some 17 multiple-choice question papers from the period 1988-1992 – by no means a complete set, but they range across the Mathematics, Further Mathematics, Pure Mathematics and Applied Mathematics syllabuses. You can find them in the “Pre-C2000” cabinet within GCE AS/A Level.
Signing up to Mathematics Emporium is highly recommended, note that it is a free website intended for the use of teachers of mathematics in secondary schools, regardless of what board you use.

My search for multiple-choice questions returned this site from Uddingston Grammar Mathematics Department, the Scottish Higher resources include multiple-choice questions, each set of questions includes an answer key.
We will finish with some challenging questions for students chasing the highest grades:

For superb resources for the Oxford Admissions test multiple choice questions see these Underground Mathematics Review Questions where you will find not only the questions but suggestions and complete solutions.
