Top 55 Free Online Tests to Check your Knowledge

Tests are a great way to check students’ knowledge of a specific topic, field, or subject. It sometimes isn’t even necessary to have a teacher involved to get test results and give grades, as tests today can be completely automated.

But even with all the pros that testing has, that doesn’t mean that assessments won’t stress students out. And there’s a whole lot of reasons for that. Like the fear of making the wrong choice, an inability to correctly understand the question, or even missing out on the review of the material included on the test.

As a result, preparing for tests can become unnecessarily tough on students. Especially if the test results bear great significance.

That’s why we decided to come up with this post—to list helpful resources that will allow you to take a practice test in dozens of fields. Trying an online sample test or two can make your preparation a lot easier, as you will at least know what to expect.
We’ve divided the article into three categories.

The first one contains resources for ACT practice tests. The second lists SAT sample tests. And the third category includes resources that offer a variety of tests and quizzes not designed for any specific exam.

Are you ready to improve your test-passing skills? Let’s do this!
