I've never had any CDs with my Bio books and only ever had one, with stats (which was useless). However, I did purchase the CD A&P Revealed separately and it was great. I saw it mentioned on the back of the text and bought it off eBay.
I am a firm believer in using the publisher sites to supplement your studying. I have found an occasional question pulled directly off the publisher sites, so I always do the tests and find the answers in the book, underlying them. BTW for 201, I never took notes. I used my text exclusively, writing in the margins and highlighting only. Find out what works for you and go with it, I tried notes but they took way, way too long. So, I ended up highlighting the stuff I would have copied down instead.
I plan on using a similar plan with Patho and have already bought my book for fall (1800 pages!!!) so I can start 'setting it up'. If you want to know what I do, Ill be glad to tell you, I'm just trying to trim down my posts! lol
