EPA 608 guide
A two-week EPA 608 study plan you can do from the van
Most people studying for the 608 are working full days. This plan assumes about 30 minutes of listening a day plus two practice papers — no evenings at a desk, no textbook.
Week one — fundamentals and the Core rules
- Day 1–2: the refrigeration cycle and pressure–temperature relationships, on audio during the commute
- Day 3–4: recovery rules and the numbers — 80/90, evacuation levels, cylinder handling
- Day 5: leak-rate rules and record-keeping duties
- Day 6: first full practice paper, timed, with no notes — this is the baseline, not the score that matters
- Day 7: reread only what you got wrong, then listen to those lessons again
Week two — types, numbers, exam conditions
- Day 8–10: the type-specific material for the certifications you are sitting (II for most residential techs)
- Day 11: second practice paper under exam conditions (no phone, timer on)
- Day 12: weakest category drilled until it stops being weakest
- Day 13: numbers-only pass — write them from memory, then check
- Day 14: light review, early night. Do not learn anything new the day before
The mistake that fails people
Reading about recovery rules feels productive; recalling them under time pressure is what the exam tests. Two timed practice papers beat five evenings of rereading. If your practice scores are stuck below 70%, the gap is almost always the number-based categories, not the concepts.
Frequently asked
- How long does the real exam take?
- The sections are timed per your testing organisation's format; the practice exam on this site mirrors the common shape — 30 questions in 30 minutes. Check the timing with your provider when you book.
- Can I pass in two weeks?
- With consistent daily listening and two timed papers, two weeks is realistic for most working technicians. The variable is not study hours — it is whether you test under exam conditions before the real thing.
