Let’s say you’re planning to take the SAT Reasoning Test. If you’re a college-bound student in the United States, chances are good that you’ll either be taking this test or the ACT (or both) in order to get into college. This is a fairly high-stakes test. It’s only offered a few times per year, and due to college application deadlines, most students only have a couple opportunities to take it. Add to this the fact that it costs $43 to take the test, and that it’s given on a Saturday morning, and you’re going to want to do as well as you can the first time you take it.

So how do you prepare? Well, you could buy an SAT Prep book. There are lots of titles to choose from, each offering the “best” advice on preparing for the test. You could take a class online. Kaplan offers one for $399. For a mere $70, you can take an online course from the College Board, which administers the test. If you’re a student in my district, you can take a before-school class for $50 that will help you get ready for the test.

Or, there’s an alternative. ProProfs.Com offers a wealth of SAT test-prep materials for free. The site offers practice tests, study guides, flash cards, quizzes, and test-taking tips for best performance. The site also offers some videos, but they’re mostly embedded YouTube videos, so access to these resources may be limited in schools.

In addition to the resources provided, the site allows teachers and students to contribute by making their own quizzes and editing the wiki. This allows students to share their successful strategies with others.

In addition to the SAT prep resources, the site also has study aides for the CompTIA, Cisco, and Microsoft certification programs. They’re also working on resources for the ACT, GRE, GMAT, and several other high-stakes tests.
