Agreed, when I was at uni a few years ago, having the lecture slides was a handy reference EVEN when I wrote my own notes during lectures.

One thing it helps with is for professors with their own special take on a subject where you have to use the exact right obscure method that only exists in their 20 year old slides and nowhere else. Or if the textbook is garbage or doesn't exist. When your course context is not the latest and greatest information, having the slides is handy for passing.
