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 timed practice exam that pulls from every topic bank at once — concept questions and numeric problems mixed together, as on the real Associate CET exam. The default, 100 Q · 120 min, is the real exam's full length; the shorter options keep the same pace of 1.2 minutes a question. Questions are drawn weighted toward the emphasis seen in the ETA practice materials (DC/AC circuits, applied systems, and electrical theory and components carry the most weight; safety is a small share), 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.
