Arduino Projects Book

Hello!
I'm looking to take the Arduino Certification exam and trying to get hold of the Projects Book to help my learning. Unforunately they cannot be sold individually, wonder if anyone could suggest a similar book to help me with some study before taking the exam.

Appreciate any comments or suggestions.

Many thanks
Deryck

IDE >> FILES >> EXAMPLES >> STARTER KIT >> (p02 through p13)

The book exists here:
