I have given it 5 stars but that applies only to the small section that I was interested in. On what I read, I would say that it was very useful, clear, and concise, which is my best recommendation. It certainly was good value. I am not sure whether I could say that any book about computers could be compelling, so I have left that out, but to be fair, I can see that it would be compelling to someone learning Excel, which is a very good program and needs to have a lot of explanation in parts. Most definitely buyable, and really uite essential for someone who did not know all therte was to know about this particular program. I am very pleased that I bought it!I have given it 5 stars but that applies only to the small section that I was interested in.
