Literally the most beginner unfriendly book i ever had the displeasure of having to read for uni. It explains some of the easiest concepts in the most confusing way possible using words that don't even make sense unless you already learned them through another source. It is difficult to even understand what is the book even saying let alone memorise it for uni. Some people are quite knowledgable but don't have the ability to convey it to others in a way that is easy to understand and this is a prime example of that
