Query: really basic. confusing descriptions

Only chapter 2&3 are worth reading. chapter one is ok if you remember no HS chemistry or physics. Chapter 4 on diodes and transistors starts well but leaves you a bit confused in the end.Chapter 5 is bad because of the missing information in chapter 4.The rest of the book is a waste.Still looking for a book on electronics that will let me have a clue as to how circuits are designed.
