Query: too broad, even for general understanding

This book gave no specifics or real depth on many of the topics presented. Clear evidence of this is seen with the end of the chapter problems, which are repeatedly unsolvable when the text is used exclusively. On numerous occasions I had to go to other texts (such as Miessler's 4th ed.) in order to properly solve and understand complex problems/theories.Further this book is very heavy and rather cumbersome for the mobile/bike-riding student.One good thing is that all answers are given for practice and end of chapter problems which is helpful.I would only recommend this book as a supplement to other more comprehensive texts and at $60 (used), it's not too overpriced to add to a collection but not necessary either, IMO.
