study advice.

[lighterxx]

Well usually what you can do is studying topic beforehand from an easier medium be it a summary book or slide show or something. Then while reading chapters you won't have concern of learning the whole topic, you will rather learn the details from it. It's also useful to have post it's and page markers ready, as you, despite what feels like, don't need every page and you can instead note down important parts to post it.
