Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Head Scratcher

This book unlike many undergrad books appears to be intentionally elusive. It's examples transcend the entire chapter instead a clear example followed by more challenging ones. I have to scour the pages for clues as to how to approach one of the end of the chapter problems and still I find myself guessing. The books structure is a mish/mash. I can't believe I have to endure another two moths of this. MBA Student.
