Thank you very much I bought the harvest of the empire book but I'm more visual learner so I'll look for video documentary too. I will also buy that other book. Did you pass that test subset v? How many times did it take you? I'm just feeling bummed that I'm so knowledgeable but this section makes me feel as a failure because I grew up in Mexican culture. I know it's not true but when I see the do not pass it made me feel really bad. Thank you got taking the time and replying.
