A free account starts the 30-minute mock, as often as it wants. The quick checkpoint above is the same, and the longer sizes come with the full bank.

The 2 hours run is the real sitting's shape and length. The shorter three are cuts of the same paper, weighted the same way. Each size shows what the bank can serve at that length, not the paper it aims at. The full sitting is 50 questions, and where a section holds fewer than its share the run is shorter by that much.

TCEQ names the Texas Commission on Environmental Quality, which licenses landscape irrigators. It appears here only to describe the exam.
