I studied for about 1 week. That might not have been enough but I passed with a 52. Good enough. I also looked at Basic Economic Essentials, a paperback book that has several chapters on Macro that kind of puts things together from IC. I was kind of crunched for time so if you have the time I would study a little longer. But on a good note, IC has been great for me and so have the Forums. Macro and Prin. of Mgt(67) in 16 days! Thanks for everyone's suggestions.
