How many did you get right?
Predicting first builds calibration — knowing what you know is a skill the exam rewards. No peeking; just your honest gut estimate.
Timed Mock Exam
A full-length, timed practice exam that pulls from every topic bank at once — concept questions and numeric problems mixed together, just like the real Associate CET exam. Questions are drawn weighted toward the emphasis seen in the ETA practice materials (fundamentals, components, power, test equipment, RF, and safety carry the most weight), so the mix concentrates where the real exam does. The passing standard is 75%. No feedback until the end, so it mirrors real test conditions.
