About CertReady
Prepare. Practice. Get Certified.
CertReady is an independent exam-prep platform for the certifications that skilled trades and technical professionals need to get hired and stay licensed. We started with EPA Section 608 for HVAC/R technicians, CDL knowledge tests for commercial drivers, and Grade 1 water and wastewater operator exams, and we add certifications based on what learners ask for.
How we write questions
Every question is original. We study the published exam blueprints, the underlying regulations and reference texts, and write items that test the same facts, numbers and judgment calls the real exam does. Each question carries an explanation and, where relevant, a pointer to the official source so you can verify it yourself.
What we are not
We are not affiliated with the U.S. Environmental Protection Agency, FMCSA, any state DMV or licensing board, Water Professionals International, or any exam provider. We never publish actual exam questions, and we don't guarantee you'll pass — but we do our best to make sure you walk in knowing where you stand.
