No, but you can read selectively.
I've done well in both my first and second year by doing this - Imo lecture reading (unless there's an exam for that module) is a waste of time I could better spend on assessed work.
I prefer to do my lecture reading for exam modules as exam revision at the end of the year, as it takes too much time away from other things to do it every week throughout the year, and I find that I remember it all far better if it's part of revision - this does mean I am not the kind of person who is cram-revising one week before the exam though. I instead focus on seminar and essay reading throughout the year, and at the minute dissertation reading too.
It's great to read before lectures and be sitting there knowing exactly what's going on, and you do get much more out of them that way, but for me time is in short supply and I must focus my efforts and work smart. Uni is a game to be played.
