On my Moodle website, I would like to grant the role of educator only 50 students. Is there a way to do this? Or can a module be made for this?

I also add PDF file with File activity and Video file with Page activity. But I want to add timing to PDF files and video files, just like in the Quiz activity. Can i do that ?
