Oregon Practice Licensing Process

What is the minimum number of correct answers required to pass the Oregon Class C knowledge test?

  1. A.
    20.
  2. B.
    25.
  3. C.
    28. Correct
  4. D.
    32.
The Why

The answer is "28."

You must answer 28 of the 35 questions correctly to pass the Class C knowledge test: 80%. Missing 7 questions is the maximum that still allows you to pass; the eighth wrong answer is the failure threshold.

Why the others miss

The traps in the wrong answers

A. 20.

20/35 is below the passing threshold. Misreading: Confuses the passing score with a much lower bar; the manual sets 28, not 20.

B. 25.

25/35 is below the passing threshold of 28. Misreading: Half-remembers a roughly 70% pass mark; Oregon requires 28/35, not a lower count.

D. 32.

32 exceeds the minimum; 28 is the threshold. Misreading: Inflates the requirement to roughly 90%; the manual states 28 correct is enough to pass.
