It’s a lot of content to get hit with at once. Just do your best to stay on top of the material. As annoying as it is, it really is very helpful to go into lecture having already read the book or watched the pre-lecture videos (if any). It makes the content more digestible to be seeing it for the second time.
It really helped to run through the objectives with a friend in the evenings leading up to the exams. We would create a giant google doc with all the content and just review it with each other, taking turns and each talking over chapters we felt respectively weak on.
