Example Input: This book was purchased as a supplement to our studies. I felt it wasn't organized very well and the questions were not related very well. It does have some good information, but needs re-organization. We got better responses with another study materials we bought instead. If you know what your studying about before doing this book, it's okay. Just don't rely on the answer sheet in the back. The other sources that we found help quite a bit. Overall it is worth what i paid for it.
Example Output: Good Review
