 No. OSSU creates guides to resources that will empower you to learn the curriculum of an undergraduate degree. Individuals who used to be involved in OSSU may be working with other organizations to offer degrees, but Open Source Society University is not involved in those efforts.
 
 ### How can I review the math prerequisites?
-Many OSSU students choose to review math topics that they have not studied recently.
-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 assessments.
-After taking an assessment, you should have a clear idea of what topics to study and where you should start with the resources below.

-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.gg/mS4GnBCdZk).

 ### 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.
