OAR Practice Test 2026 — Free OAR Exam Prep Questions
The OAR is the officer-aptitude score the Navy uses for Officer Candidate School and other non-aviation officer programs. It is built from three ASTB-E subtests: Math Skills, Reading Comprehension and Mechanical Comprehension. Our practice questions mirror those three subtests and explain the method behind every answer.
