Hi all , I take my exam for the C license in 2 weeks , and I’m looking for any tips/advice on what you guys did to pass. I’ve been studying a lot , mainly primary treatment and process along with chlorine/disinfection. How difficult was the exam for everyone , what types of questions were on it , what did you study; the textbook, videos , quizlets? Anything helps , thank you!!
