So far I have used this book the most of the 3 Excel books I bought. It is easy to follow the instructions and have the results work. I was able to create column functions with little to no effort with this book.
This is a well written and easy to follow guide to excel. Covers all the basics, but be warned that you have to have the actual program to use the CD. My workplace has the program on the office computers and when I got an office position I wanted to brush up on Excel before I transferred, but since Excel is an expensive program I didn't own it on my home pc. So the CD wasn't much use. Was able to study the text and get some useful pointers and tips on shortcuts tho.
