Online Refresher

Online Refresher Courses Math - 15A, 15B, 15C, 15E, &15F

Math 15 refresher courses are ideally suited for students who have not taken math for a long time and want to refresh their skills. Math 15 courses offer students a one-unit, pass/no-pass way to refresh their math skills without the commitment, cost, and academic risk of a full math course. In addition, they can also be used to remove a block from re-taking a course or to waive a course prerequisite. Math 15 courses are open-entry, open-exit, and customized for self-learning. The learning is delivered fully online, however, students are encouraged to access the course in the Math Center, where tutors are available. Math 15 courses have no prerequisite, can be taken simultaneously with other math classes, and can be re-taken several times.

Challenging a Prerequisite

A student may challenge a pre-requisite by finishing 90% of the course goal material and passing a Math Center final exam with a grade of 70% or higher. For Math 15B and Math 15C, students must also pass both the Algebra and Geometry components of the courses with 90% in order to challenge a prerequisite. However, students should be aware that the higher-level Math 15 courses (B and C) are very challenging. Although they are listed as one-unit classes, students should expect to spend time equivalent to a 5-unit class in order to complete finish the course.


Courses Offered

  • Math 15A - Pre-Algebra, material equivalent to Math 38
  • Math 15B - Elementary Algebra and Geometry, material equivalent to Math 46
  • Math 15C - Intermediate Algebra and Geometry, material equivalent to Math 96


Grading Procedures

Math 15 courses are offered pass/ no pass only.


How to Approach a Self-Paced course

Although the self-paced refresher courses offer marvelous flexibility in access, scheduling and pacing, many well-intentioned students find that they are not prepared for the demands of these formats. Success in an online self-paced refresher course requires strong doses of the following personal characteristics:


You must be highly motivated and able to learn on your own to succeed in this course. Otherwise, you may find yourself attending less and not accomplishing your math goals.


It takes a lot of self-discipline to log in regularly when you are given so much flexibility. It is easy to forget about an online course. It takes a disciplined student to set up a regular schedule and stick to that schedule.

Good Time-Management Skills

It requires a great deal of time-management skill for most students to find consistent time each week in their busy schedules for studying math. You may have to give up or cut back on some social or recreational activities, hire a baby-sitter, get help from your friends and family, or simply be more tenacious about setting a schedule and sticking to it. If you are determined to finish this course in one semester, you need to find a way to make it happen.

Good Reading Skills

A self-paced course puts a heavy demand on your reading and comprehension skills. A large portion of your learning will come from reading the learning activities, working practice problems, and taking assessments online.

Solid Internet connection and functional computer

Online students are also required to maintain a functional computer and obtain reliable online access. Self-paced online courses are not for everyone. If any of these skills are not already part of your personal strengths, then you should consider taking the course in a lecture format or coming back when you are better prepared. On the other hand, if you do have these skills and you are ready for a challenge, then read on.



There are no prerequisites for Math 15 courses. You may take them in conjunction with other classes and you may retake a course several times if necessary.


Repetition Violations

A student may remove a repetition violation by finishing 90% of the course goal material of the appropriate math 15 course. No final exam is required. Math 15 courses are ideal for students facing repetition violations and are blocked from re-taking a needed math course. These students are required to take the course preceding the course from which they are blocked. Instead of taking a full course, students can take the corresponding Math 15 course. Students blocked from taking Math 46 should take Math 15A, those blocked from taking Math 96 should take Math 15B. Since there are no repetition restrictions on Math 15 courses, students can overcome repetition blocks without the threat of further punitive action.


Required Course Materials

Math 15 courses are completely online and all instruction takes place online in. There is no book to buy and access to the program is free to all students registered for the class.



Trained tutors are available throughout the day in the Math Center (L-208). The tutors are there to help you, but it is up to you to contact them if you are having difficulty. Sometimes, you'll find that a few words from a tutor can help clear up problems that might take hours to sort out on your own. If you feel that you need help, just bring your CSID card to the Math Center. Online tutoring is available as well.
