Prerequisite Skills
Students enrolled in MAT 140 frequently have difficulty due to a failure to retain necessary prerequisite knowledge. One way to address this is to make an intensive effort to review prerequisite skills prior to beginning the course. You can take a free trial assessment on ALEKS to help identify topics that would be helpful for you to review. Select the "Precalculus" course. After taking the assessment, you can decide if it would be beneficial for you to pay $17.95 for a month of access to the learning mode of ALEKS to review necessary prerequisite skills.
There are also online worktexts for ALEKS that you can use to review:
The text publisher also offers a brief review of algebraic skills that will be used in the course on the text web site. The Algebra Review contains a set of exercises that focus on important algebra skills that recur often in analytical solutions of calculus problems. These exercises enable you to brush up on algebra skills, like factoring, simplifying rational expressions, and rationalizing denominators.
There is also an online Precalculus tutorial called "Visual Calculus" created at the University of Tennessee. You will want to first visit their help page for needed plug-ins.
Here is a link to information about preparation for Calculus.
There is an excellent free site at: http://mathonline.missouri.edu/ . Click on one of the servers and select what type of problems you would like to review. You can get solutions to all the problems by clicking on the appropriate link at the bottom of the page.
