Query: Must be the dumbest colleciton of blah ever printed.

I could not believe that this book oculd get worse as it went on. I admit, towards the end, with less than 1/5 to go, I quit. It was hopeless. There is nothing redeeming about this book. This is a true waste of paper. I feel for the tree that gave its life for this wasted effort for everyone involved.
