Unfortunately we have not had the resources to update the revision nutshells this year so rather than publicise possibly inaccurate information we have removed them from our site.
There are many useful resources from SQA and BBC Bitesize listed on the Parentzone Scotland page https://education.gov.scot/parentzone/learning-at-home/Supporting%20study
Happy to provide copies of the old versions if you email enquiries@npfs.org.uk
