Instruct: Classify Amazon reviews into positive or negative sentiment
Query: I agree with other reviewers

Take my suggestion: "Don't ever buy this book". I am a second year student and my school use this book as a text for Introduction to EE. Since my instructor is so bad in explanation, at the very beginning, I thought, I could rely on this text for understanding. I HAVE READ EVERY SINGLE WORD IN THE FIRST TWO CHAPTERS AND REPEATED SO MANY TIMES AND STILL, I DON'T COMPLETELY UNDERSTAND THINGS. Very vey hard to follow. If you don't believe what I said, read it yourself before buying it.
