Top Law Schools

I've seen many threads stating that Acing is pretty good. However, after looking at a sample, it seems the majority of the book is doctrine. My professor teaches corporations in a policy-type format and has stated the exam will be similar. Any supplements that can give me a good idea about policy of corporations?

Thank you in advance!

My professor recommended this:

William A. Klein, John C. Coffee, Jr., & Frank Partnoy, Business Organization and Finance: Legal and Economic Principles (11th ed. 2010).
