I took the exam in Austin Texas I got sick during the exam because I believe I took bad water. They were having an issue with water in that city. I got up from my chair and ran to the restroom and threw up. I felt like garbage. It had nothing to do with being nervous. Anyways I thought the exam focus in areas that I didn't even study. some of the calculations were not coming out like I was expecting even though I had the formula in front of my face. What did you guys think?
