Great for studying!

"I had to knock off one star just because element 1 was repeated in both books. I think I would have rather had a book that has all 4 elements in one for the combined operator's/maintenance license. I can understand that the two books are for each license separately, but for those of us going for both together, it would be nicer to have one book."
