Before you start

The 4-hour clock keeps running in background tabs and across reloads; when time runs out, your answers are submitted. There are no paused breaks, as on the real exam.
Every question has four answer choices. Unanswered questions count as wrong, so answer every one; there is no penalty for guessing.
25 of the 175 questions are unscored and placed at random, as on the real exam, so answer every question as if it counts.
