Where can I find online practice tests?

An excellent database is Learning Express Library.  It has a fully-searchable collection of test-preparation eBooks, covering elementary school, middle school, high school, college preparation, GED preparation, tests for college students, U.S. citizenship, and job search/workplace skills. A Spanish-language section is also available.

Go to the library’s webpage and choose Find Resources.

Select Online Databases by Title and select L to find Learning Express Library.

You can search using your phone, tablet, or laptop/computer by look at the particular module (College Center, College Preparatory, etc.) or you can type the name of the resource you need in the search box at the top of the page (e.g. PRASIX, GRE, SAT, etc.).  There are great videos to help you navigate this resource.
