One of the problems we encounter while teaching college algebra is that many students do not have the mathematical skills which are essential for success. This is true even though the prerequisite course (Intermediate Algebra) has been passed. To address this problem, the Mathematics Department of the University of Arizona decided to do the following. Write a computer program which a student can use before starting college algebra. This program would quiz the student on all sections of algebra which are essential to college algebra. The quizzes cover linear equations, exponents, functions, and factoring. The whole purpose of the program would be to hone the student's skills in those parts of algebra which are essential for success in college algebra.
