Query: Waste of my money

I had to purchase this particular book for one of my college design classes since it was not available at our campus bookstore. It was a WASTE of my money and time to buy this book! My professor at the time was a weird guy and he pulled out some of the activities out of the book to use during class. Turns out that no one used the book either. It was a real BORE... and I couldn't sell it anywhere after the quarter ended. So I gave it to my 15 year old brother in hopes he would enjoy it more than I did.
