This resource is useful for those teaching or tutoring students using Khan Academy.
Unit tests on Khan Academy are all online, and usually only include multiple choice answers. I have created a series of 'unit tests' that can be done in class on paper or electronically.
This is a physical test that can be printed out and used as is, or edited to suit your needs.
Khan Academy is a non-profit organization that provides all it's resources for free. I highly recommend it for helping students to become independent learners.
