Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Very poor effort

These cards are essentially worthless. If you are expecting to learn anything from them, be prepared to be disappointed. They look like someone went through a medical dictionary and put words on one side and the definitions on the other, which I suspect is what happened. Only very marginally useful as a quick review of material you already know. Very low yield, and unfortunate, as they had so much potential.
