Our quizzes are helping you to develop the skills and knowledge required to take the TSI Math subtest successfully. These math quizzes address solving problems and some questions can be slightly different from problems found in the book.

For these problems, you’ll have to adapt the things you’ve learned to be able to solve these new problems.

When you have missed a question, our quiz will show you the correct answer which allows for self-diagnosing the mistake.

Then, you can work on similar problems until you understand the topic and answer the question correctly.
