Delivery Format
Computer-adaptive
The OAR is the MST/RCT/MCT portion of the ASTB-E and is delivered in APEX computer-adaptive format. Navy Medicine's current FAQ says the OAR takes about 1-2 hours, has no fee, and uses program-specific minimums rather than one universal cutoff. Current 2025 MyNavyHR program authorizations show example minimums of 42 for SWO/Supply, 45 for Civil Engineer Corps, and 50 for Intelligence. Navy Medicine does not publish fixed official section percentages, so the practice mix here follows common OAR prep emphasis rather than an official weighting chart.

Frequently Asked Questions
What is on the OAR?
The OAR consists of three subtests: Math Skills Test (MST), Reading Comprehension Test (RCT), and Mechanical Comprehension Test (MCT). It is the non-aviation portion of the broader ASTB-E and is commonly used for Navy OCS and staff corps applications.
What OAR score do I need?
There is no single official passing score for every Navy program. Navy Medicine says minimums differ by program and service, and current MyNavyHR program authorizations show examples such as 42 for Surface Warfare and Supply, 45 for Civil Engineer Corps, and 50 for Intelligence. In practice, many applicants aim for the mid-40s or better to stay competitive.
How many questions are on the OAR and how long does it take?
The official APEX version is computer-adaptive, so Navy Medicine does not publish one fixed item count for every examinee. For planning purposes, many prep sources still describe the OAR as roughly an 80-question exam, but the official FAQ is clearer on timing than count: expect about 1-2 hours total.
Can I retake the OAR?
Current Navy Medicine guidance states that candidates are limited to three attempts on the current OAR/ASTB-E series and that at least 30 full calendar days must elapse before a retest. Because policy details can be updated administratively, confirm your current eligibility window with your recruiter before scheduling.
Can I use a calculator on the OAR?
No. The official ASTB FAQ says calculators are not allowed. You are given scratch paper, and the test is designed to be completed with mental math plus the formulas provided.
