Water testing seems to be the big deal. I think that we need to know What each test means, and how to do it. They should give us the necessary supplies for the actual tests. The water tests they give us will probably have directions.

I hope that they refine Environmental Chem this year. I took it last year and the guidelines were kind of vague so the regional and state tests that I took were totally different. - They didn't even seem like the same event! Talk about frustrating....
