I don't think EK 1001 Bio was bad. It wasn't great for passage based practice but it was good at letting you assess your weaknesses. TPR Science Workbook has really great passages of varying difficulties that I liked. TBR was varied, they were good at some of the crazy passages but some passages were just not great and all seemed hard, which the real MCAT isn't really like. Overall I'd say TPR had the best practice for Bio. Also, I saw some of you guys mention scores and percentages, honestly I wouldn't worry about how you score but use it and practice to perfect your skills and learn the material. Of course you should score yourself to see where you are and so you can see weak areas/trends but don't put faith in anything other than AAMC to predict scores so don't worry about all the percentage stuff too much.
Hope this helps,
