Past exams, worked
CBP publishes each exam and its answer key after the appeal window. Here are all 6 released so far, 480 of 480 questions worked through. Every answer was checked by a script against CBP's official key, and every quote was checked against the pinned books.
Best use: sit one whole exam on the 4.5-hour timer first, without looking at the walk-throughs. Then read the walk-through for every question you missed or guessed. CBP repeats question types far more than exact questions.

Exams and keys from CBP's past exams page. Each exam used the reference editions CBP listed for that sitting. Where a later edition changes the answer, the walk-through says so.
