This is how almost all the lectures I attended in the mid 70s (Physics, Exeter Uni.) were done. The one useless lecturer who just read the set book we tried to get fired and when that didn't work just formed a rota and noted the page numbers so that we could just precis the relevant pages at leisure. He also set the exam in the same way and as all the exams were open note we all passed with flying colours.

The other course were more challenging and more interesting.
