Due to the new Higher Design and Manufacture course only being run for 3 years currently, there are only a small number of past papers and exemplar papers available from the SQA. Below, there are links to the SQA past papers available and also a link to the SQA website to access the marking schemes. There are also a range of old Higher Product Design papers which are very similar to the new Design and Manufacture course that can also be used for revision.
Your teacher may issue these as homework tasks but you should also make use of them for revision material. You can use the marking schemes to mark them yourself or hand them into your teacher for marking.
