This Algebra test is not meant to be done in one sitting. If you can accomplish that -- good on you -- not only do you know your algebra, you've become efficient and precise, so you're ready to tackle other things! Check out some Analytic Geometry.

This test is meant chiefly as a comprehensive review of the material in the lessons of the Algebra MathRoom to help the student evaluate his/her familiarity with the material. It should also serve to pinpoint weaknesses or topics that could use a little more practice. In such a case, go back to the Algebra MathRoom and review those topics.

You will find no multiple guess questions on this test. I despise them. They encourage you to "guess" rather than solve. You should write a clear response for each question. Your response should be properly presented in conventional math format.

Before you start, you might check out the article entitled "So You're Writing a Math Exam" in MathRoom Musings. And here's a link to the solutions .
