FAA exam rules: −0.25 marks per wrong MCQ. Blank is better than a wild guess.
Simplify the ratio 18 : 24 to lowest terms.
If 3 : 5 = x : 20, find x.
Pass each skill by answering correctly on 2 of 3 checks (fewer if fewer are available). Practice questions above are rehearsal — only mastery checks count toward progress. Retry wrong answers until you succeed.
Wrong answers show the FAA −0.25 penalty as a reminder — mastery still allows retries.
