MA 15300 is intended for students who have successfully completed at least two years of high school algebra. Students who are unsuccessful in passing this course typically are those who are unable to do the basic skills shown below. Take a look at the following kinds of problems. If these problems are challenging for you or do not look familiar, discuss your options with your instructor. Based on your major, you may be able to take a course with less prerequisites and higher success rates, such as STAT 12500 or MA 14000.
