Resources Link is an e-resource, provided by OCR, for teachers of OCR qualifications. It provides descriptions of, and links to, a variety of independent teaching and learning resources that you may find helpful.
In Resources Link you will find details of independent resources, many of which are free: where this is the case this has been indicated.
If you know of other resources you would like to see included here, or discover broken links, please let us know. We would also like to hear from you if have any feedback about your use of these, or other, OCR resources. Please contact us at resources.feedback@ocr.org.uk.
We leave it to you, as a professional educator, to decide if any of these resources are right for you and your learners, and how best to use them.
