Negative Positive
Title: test problems not covered in tutorial part of lesson.
Review: I've encountered problems with this book, a lot of the types test problems at the end of each lesson are much more complicated than the problems given as examples in the tutorial part of the lesson, and I'm having a difficult time trying to figure out the correct answer or how the creator of the book came to the answer given to some of the problems at the end of the chapter.
