We encourage that students in the course choose preprints or other open access published papers within their field. Sometimes they choose a paper that is not open access and you as a mentor might not have access to it. In these situations just assess the review based on the way it is structured and the clarity of the comments.

However, if you prefer you can ask the student (if you have their contact details) or Publons to send the full text of the paper. You could also try and download the Kopernio browser extension and it might find an open access version of the article for you.
