It's been totally worth it already. I have seen areas in my instruction that need improvement just in these first few days. I have also seen areas that I've done well in, and am thus a bit relieved too. I've met people with similar backgrounds, interests, and concerns from all across the country. I have found more resources and even been given a glimpse of the future of the test.
Today, I received a well-needed lesson in navigation (Seriously? Our hotel is straight down the street from the convention center?). I also made plans to eat at an Ethiopian restaurant on our "dine-out" night - Day Five). And I spent some time floating in the hotel's indoor/outdoor pool. Now I need rest.
