We also learn a lot of things both in this book of Scott Kelby. Yes, it is number 2 of a collection of 3 books (so far). Certainly he returns on some points mentioned above in Volume 1, but it is for developing what is always interesting. He does not beat around the bush with complicated explanations, and instead gives expert advice that are good to take! Personally I have the 3 books I reread frequently depending on the type of problems I have, and it helps me.
