A self-paced precalculus course offered on edX by Arizona State University (MAT170x) that uses the ALEKS adaptive system to assess what you know and fill gaps before teaching the material. Commenters note it is free and pairs with an earlier college algebra course.

Commenters say it is a free way to find and fix gaps in math knowledge using the ALEKS system, and that it is a good next step after algebra.

   Whenever I try to catch up with maths (in Khan Academy and elsewhere), I always end up in an awkward state where I keep recursively researching less and less advanced subjects because of gaps of various sizes in my fundamental knowledge. It's incredibly demotivating.

   Try this course: https://www.edx.org/course/college-algebra-and-problem-solvi...

   It uses the ALEKS system which identifies your weak points and brings you up to speed. Take notes during the process so you have something to reference in the future and won’t forget what you learned.

   After you knock out the algebra course you’ll be ready for the precalculus course: https://www.edx.org/course/precalculus

   The ALEKS system in the Precalculus course will also remediate anything you forgot from the Algebra course.

   Hopefully this will help give you the confidence to go after more advanced maths once you finish both courses. Be kind to yourself, math, like anything, is a skill, it takes time and practice.

   If you sign up for the EdX Precalc class https://learning.edx.org/course/course-v1:ASUx+MAT170x+2T201... they will let you use ALEKS for free.

   Sign up for pre-calc class on edx.org it is free and offered through ASU. First you take the test to see where your knowledge stands then you learn based on that test.

   They use ALEKS learning which is a great tool to learn online. Make sure to take notes and do the problems.

   My advise don’t pay for math at community colleges because they use the same tools but you have to pay somewhere between 300 to 500 for courses which is waste money.
