Prepare for the Navy OAR

The Officer Aptitude Rating uses three parts of the ASTB-E: Math Skills, Reading Comprehension and Mechanical Comprehension. Certain non-aviation officer programs use OAR. Aviation applicants need additional ASTB-E components; this practice covers the three OAR subjects only.

Navy guidance says OAR takes about 1–2 hours in APEX. The adaptive test can vary in question count and difficulty. Our full practice has up to 60 original questions: 20 per subject, with editorial clocks of 30 minutes for math, 30 for reading and 15 for mechanical. Those are practice settings, not a claim about the exact official blueprint.

Yes. Questions start at intermediate difficulty in each subject, then move up after a correct answer and down after an incorrect answer within three editorial difficulty levels. This is a transparent learning rule, not the Navy’s proprietary adaptive selection or scoring model.

No. Navy guidance says you cannot skip questions or change earlier answers. Our practice follows that forward-only sequence. Short drills explain each submitted answer. Full practice saves all feedback until the end, with separate clocks for the three subjects.

The official OAR does not permit a calculator. Navy guidance says relevant formulas and scratch paper are provided. Practice without a calculator. Our on-screen formula reference is a study aid, not a reproduction of the official formula sheet.

The required OAR score depends on the officer program and current selection requirements. Our accuracy and demanding practice goals are learning feedback, not an official OAR score or a prediction of selection. Check the current requirements with your recruiter.

One OAR pass covers all 12 short drills, their replays and full OAR practice for the selected duration. Where trial access is included, each short drill has one free attempt. Other assessment categories have separate passes. Saved results and explanations remain available after your pass ends.

There are 288 original practice questions, 96 per subject. Selection favors less familiar questions within the topic and difficulty being practiced. Questions can repeat as you work through the bank; use exposure and difficulty alongside accuracy when comparing results.

This covers Math Skills, Reading Comprehension and Mechanical Comprehension. It does not simulate aviation knowledge, personality measures, listening or flight-control tasks. If your invitation requires the full ASTB-E, you also need preparation for those additional components.
