I've been using it for a couple of weeks now and am not impressed at all. I have found so many errors in the example problems and have wasted so much time trying to track down whether I made an error or PPI made the error. I have reported them all and not a peep back.
So any other good example problem sites? I'd rather have it online than buying yet another book.
