Frequently asked questions
Is this an official OPT&C examination?
No. AptNexa is independent and is not affiliated with or endorsed by OPT&C, the University of Guelph, MECP or a pesticide authority. This is an original study resource.
How does the practice format compare?
OPT&C’s 2025 Exterminators guide describes 50 multiple-choice questions in each part: CORE is one hour closed book; the category-specific module is 90 minutes open book. It gives a 75% passing mark for each part. Our 38/50 practice benchmark is the first whole-question score at or above 75%. This mock does not reproduce the official question bank, topic weighting or assessed difficulty.
When can I see the answers?
Immediately after submitting. Your result includes a complete answer sheet, explanations and a topic breakdown. Email delivery, when available, is an optional next step.
What should I study after the mock?
Review incorrect and guessed responses, find the relevant concept in your official reference, and explain why the best answer fits. Use the full manual alongside practice.
