Task: Sentiment Analysis
Input (English): Terrible Textbook . I am only partway through my organic chemistry course, but already I know enough about this book to give it a very negative review. It simply does not explain topics well enough. Also, The problems at the end of the chapters are simply not difficult enough to prepare you adequately for exams.  Although I've never used any other textbook, this one justs seems horrible. I'm generally an excellent student and can learn from many different types of texbooks, but this one is just horrible.    I referred to 'Organic Chemisty as a second language' by David R Klein for a clear understanding of many topics such as fisher projections, asid base strength, predicting substitution and elimination reactionns, resonance, drawing chair conformations, determining the configuration of a stereocenter, and many other basic concepts which are not explained well in this textbook.     If however, you are going to use this book, I would highly reccomend buying the solution manual, it is difficult to use this book without it. The solutions manual (4th edition) repeats each question before giving the answer, so it also a valuable aid to use even without the book itself.
Output (English): NEG
