When I was an undergrad (2008-2012) I don't think I even had any classes that were given as PowerPoint slides. If they had been though, I don't think I would have felt bad asking for them - they definitely could have helped jog my memory! Notes aren't always perfect...

I was in school (2011-2016) and almost all professors had a wiki or moodle where we could find all their slides and documents.

I noticed that the rare few professors who didn't upload their powerpoints, were mostly the ones who would just recite the content of their slides in class (almost) word-for-word.
