Litmus Tests
A litmus test is used in Chemistry to determine if a solution is acidic or basic using litmus or litmus paper. Litmus testing is so common and well known that the phrase is also used to mean something that is a strong indication of future success or failure.
From a math perspective, I have provided some practice tests that can be used as a litmus test to determine if you understand the content. A few samples are available here but there are more that can be accessed from Google Classroom using the code at the top of this page.
Be sure to check the solutions that follow.
