I made a mistake of studying definitions to much. Knowing the meaning is suffice (in fact I knew the meaning of 99 percent of the definiions before I read it).
I studied for about 3 solid weeks before testing. I took about 100 pages of notes. I would recommend the same. Focus on anatomy and the exercises. I glanced over the exercises and suffered because of it.
Make sure you read the last few chapters and have a general understanding of the business side.
Also memorize the OPT model, they have a lot of questions regarding that.
