As I said good advice though for my very social engineering daughter the library was a BAD place to study. Her friends were all there and if she tried to study on a " quiet" floor she felt more like she was being noticed as excluding herself which made things awkward. Friends would seek her out for breaks. She found it was much much better to study in her room. Individual circumstances need to be considered as is always true.
Also she mentioned that for several classes studying from the book was a waste of time it was her notes from lectures only that were important.
