They are random readings, the bad ones were right after lunch. The school was on my primary school list. After I was a week out from completing the program they charged me extra money and made me sign a 64-page contract. They wouldn't let me go to my internship until I signed and paid. I could have sued but I decided to get on with it and did those blood tests under duress. Now I have an all day Friday class helping science students to pay for the phlebotomy class.
