There is a free resource online for you to learn courses on your own. Go to https://www.myopenmath.com/info/selfstudy.php to learn more.
If you want to learn some math at your own pace, you may do that on your own, without being in a class at MiraCosta College. There are free classes where you may learn the material online, etc. Once you feel confident you have mastered the material, you may take a placement test to pass into a higher math class. More info is below.
Go to MyOpenMath.com and register as a new student. Then Click on Enroll in a New Course. Choose the self-study course you want from the pull down menu. You can study prealgebra, beginning and intermediate algebra, trigonometry, or precalculus. You can enroll in all of them if you want.
Another option is to simply watch all of my videos in order for each chapter of the book I used for my Beg and Int Alg online classes. Go to this page.
