Online practice tests and study guides can be accessed through Milner's Mometrix eLibrary database. If you are off campus, you will be asked to log in with your ULID and password to access Mometrix.

If you are browsing, scroll through the list of available exams until you find the one you need. There are two types of materials on Mometrix:
If you prefer print guides, you may be able to get copies of military service exams from other I-Share libraries (ISU is part of a consortium of approximately 80 Illinois academic libraries). To find and request titles from other libraries, you can watch this tutorial.
To find guides, do a title search for "[name of exam] exam" (without the quotation marks). For instance, a search for AFVAB exams would looks like this: armed forces vocational aptitude battery exam (the acronym will also usually work, but it's best to try both).
You will need an I-Share/VuFind account to request items from other libraries; if you have not set up that account, please watch this tutorial.
