Frequently Asked Questions

Common test scoring questions answered.

Missing 3 out of 20 means 17 correct answers. (17 ÷ 20) × 100 = 85%, which is a B grade.
2 wrong on 25 questions = 23 correct. (23 ÷ 25) × 100 = 92%, which is an A-.
To get an A (93%), you can miss at most: on a 20-question test = 1 question (95%). On a 30-question test = 2 questions (93.3%). On a 50-question test = 3 questions (94%). Use the calculator above for your specific test.

No — calculators are not allowed on the ASVAB. Both the paper-and-pencil version and the computerized CAT-ASVAB ban calculators on all sections, including Arithmetic Reasoning (AR) and Mathematics Knowledge (MK). You will be given scratch paper for calculations. Practice doing mental math and long division to prepare.
No. The ASVAB does not provide a calculator for any section. This is by design — the test measures your raw arithmetic and mathematical reasoning ability. To prepare, practice multiplying, dividing, and working with fractions and percentages by hand. There is no exception for the CAT-ASVAB (computerized version) either.
