Unfortunately, it isn't possible to recover a deleted course or it's assessment results. We recommend archiving courses instead of deleting them, which allows you to revisit the results!
Although there is no guarantee, it is possible to recover a deleted assessment. Please contact the Akindi team via our live chat and we'd be happy to assist you.
Regardless of deleted course and deleted assessments, you are always able to recover uploaded test sheet PDFs, by going to the 'Uploads' tab on the left and panel and clicking the 'Download' icon next to the PDF you wish to recover.
