 ## New To Programming
 
-- [The Missing Semester of Your CS Education (MIT)](https://missing.csail.mit.edu/) - Ths course is aimed at teaching students how to use their computers. [Something often overlooked in CS curriculum](https://missing.csail.mit.edu/about/), it gives them a hands-on introduction to tools they will use in a variety of situations such as their command-line environment and version control with Git.
-- [Harvard University's CS50](https://www.youtube.com/playlist?list=PLhQjrBD2T381L3iZyDTxRwOBuUt6m1FnW) - Harvard's CS50 Course is a great way to learn the basics of programming, with each class introducing the learner to a different programming language in order to solve problems, starting with Scratch and ending with JavaScript.
-- [Programiz](https://www.programiz.com/) - This website offers beginner-friendly tutorials on a variety of programming languages with examples.
-
-## Python Programming Resources

-## Apply Your Knowledge
-
-- [Exercism.io](https://exercism.io/) - Community backed and open source, Exercism is a great place to learn and get feedback on solving problems. They offer the ability to work with or without a mentor and it focuses on test-driven development. As an added bonus, retrieving problems and submitting solutions is done through a command-line interface.
-- [Codingbat](https://codingbat.com/) - A great place to start if you're not used to solving coding challenges, with the ability to do so in both Java and Python.
-- [Simplified Interview Questions](https://simpleprogrammer.com/programming-interview-questions/)
+1. [The Missing Semester of Your CS Education (MIT)](https://missing.csail.mit.edu/) - A series of hands-on introductory video tutorials to tools they will use in a variety of situations as they learn to write code and work on projects in school or as a professional.
