Higher Maths Past Papers

1 Introduction
It is hoped that this document will make it easier to find past paper questions, both for teachers
and students. I will do my best to keep this document up to date and include new past paper
questions as they become available. If you spot any mistakes, or want to suggest any improve-
ments, send me an email at john.macbeath@wickhigh.org.uk. I am more than happy to send you
the Tex file used to produce the document so that you can modify it as you wish.
Sincere thanks are given to Mr. C. Davie at Glenrothes High School for his extensive assistance
in producing this document.
2 How to Use
The table on the next page contains links to questions sorted by topic and year. Clicking on a
link will take you to the page of that question. The marking instructions follow directly after
each question or section of questions where more than one question is on a page. To return to the
table click on Back to Table at the top or bottom of any page. Trying to navigate the document
without doing this is tedious.
Remember - Paper 1 questions are non-calculator, while Paper 2 questions are calculator questions.
Note also that Specimen Papers (SP) are put together from previous past paper questions and so
it is possible you may see the same question twice.
Before starting any past paper questions I recommend that you print a paper copy of the Higher
Maths Sheet to avoid wasting time. A copy of the Formula Sheet is available on page 3.
