Straight answers
Is this an official EPA 608 product?
No. Techunique is an independent practice tool and is not affiliated with any certification body or licensing board. It supplements official study materials; it never replaces them.
How is this different from question banks?
Question banks are static lists you eventually memorize. Here every scenario is generated fresh against the exam blueprint, the difficulty adapts to your answers, and the coach explains the why behind every miss on the spot.
What does it cost?
A real practice session is free every day, forever. Exam tracks, timed mock exams, and unlimited sessions are part of Pro at $19 a month (or $149 a year) with a 7-day free trial.
