For those of you in the next Brasilia class...
At the hotel where you will be staying there is a room on the second floor with a paper tiger to practice flows. Also, a few of us left some catering items, crackers, plates, ziploc bags, laundry soap, etc., so be sure to check out the room before you stock up at the grocery store.
The best advice is know your EP's and limitations, limitations, limitations before you show. With the amount of new info you will have to start to chew once you hit class, you will do yourself a favor if you know that stuff cold before you show.
Good luck!
