-(Math 1, 2, 3 covers all of algebra, pre-calculus, high school geometry, trig, stats. It interleaves the order of these topics.)
+OSSU recommends to use a few resources for such a review: [Professor Leonard](https://www.youtube.com/@ProfessorLeonard/playlists) for lectures, [OpenStax](https://openstax.org/subjects/math) for textbooks, and [Khan Academy](https://www.khanacademy.org/) for assesments.

+When watching the lectures it is important that you pause before each question and work it out yourself, or try again after you understand the process.
+After you complete a chapters worth of lectures, you should complete the [chapter review exercises](https://openstax.org/books/precalculus-2e/pages/1-review-exercises) found at the end of each chapter in your textbook.
+Use your grade to determine what you need to review. OpenStax orders their review exercises by chapter section, allowing you to hone in on what you need to practice.
+Practice what you have not mastered by:
+1. Going to the proper section in your textbook and working on the examples as they have full answer explanations.
+2. Rewatching Professor Leonard's video on the subject, working through the examples with him.
+3. Searching [YouTube](https://www.youtube.com/) for another POV on the topic, again working through the examples with them. [Khan Academy](https://www.youtube.com/@khanacademy) & [Organic Chemistry Tutor](https://www.youtube.com/@TheOrganicChemistryTutor) are great resources for this.
+4. Doing the section exercises in your textbook.
+5. Asking for help in the relevant [Discord channel](https://discord.com/channels/744385009028431943/744971809056751687).
 
 ### What is a good course to learn a particular language?
 OSSU focuses on finding the best courses to learn computer science topics, and isn’t focused on finding language specific courses. If you are looking to learn a particular language or framework there are two great resources to check.
