Instruct: Classify Amazon reviews into positive or negative sentiment
Query: not bad, easy system

This book starts out simple and builds on itself as you progress. It covers a broad range of med terms, with about 30 pages in each chapter and a good end of chapter review with different types of quizzes. The CD is also by chapter and has games to test you and also an area you can listen to the vocab words for pronunciation. My "plastic comb" version (not the spiral bound for more $) is falling apart after 2 semseters of use though.
