@jk my greatest fear is a lecturer using turnitin, which seems like dodgy software anyway.
Libreoffice (and Collabora) are all I use and I can see pictures etc being ruined with a dodgy reformatting. Thankfully, they allow just emailing the lecturer directly.
Pleased to hear it got through though, well done!
Not sure that it warranted such an honourable score but not going to complain.
