Study free online. Pay for the format that helps you finish.

Everything below is built from the same verified question bank, checked against 40 CFR Part 82. What changes between the tiers is how much of it you get on paper, and how much extra drill material comes with it.

Plainly, so you can pick without guessing. The $29 pack is the compact exam-week version: the numbers sheet, two full practice exams and worked answers, 66 printable pages. The $59 guide is that plus 0 advanced scenario drills organized by Core and Types I to III, which the $29 pack does not include. The $89 tier is the same content as the $59 guide, printed and shipped. Those two really are the same material in two formats; the $29 pack is a smaller book.

The 305 practice questions on this site stay free. Permanently. Work through the free 100-question simulation first. If you are already passing it comfortably, you do not need to buy anything.
