The SQA publish have published the last four exam papers on their website.
Working through the past paper question can be a useful way to revise, whilst getting a feel for the types of questions that you might find difficult.
In addition to the Past Paper the SQA also publish a Course Report. This document outlines the questions that candidates answered well, and those that candidates found challenging - along with why candidates found the question challenging. Using this can help direct your revision to the trickier concepts.
Below I've given direct links to all Past Papers, Marking Schemes & Course Reports (where available). For some questions I have recorded Walk-through videos, where I demonstrate how to answer the question.
Many of the questions in this paper now form the 2023 Specimen Question Paper.
