Preparation does it!I passed the stringent exam for Connecticut Department of Energy and Environmental Protection (CTDEEP) Class IV Operator on the first try. Phil Bassett was correct: Preparation is the No. 1 way to ensure success with certification examinations (“Passing the Test,” September TPO).I consistently studied for the exam for five months. I started by arranging a study location and gathering the materials. I made flash cards for all the key vocabulary words and formulas. I reviewed specific “sewer math” problem sets. Then I went online and gathered more exam-specific materials.Lastly, I spoke to 15 current operators about their experience
