Hi John,

Yes, we do plan on adding new courses in the future! Unfortunately, we're a very small non-profit team, so our efforts are currently focused on adding core K-12 courses (meaning a Mechanical Engineering would be outside of our current scope).

That being said, we're always working on creating new content and we would love to expand into additional subject areas and education levels once we have the resources to do so!

I hope this helps! Please let me know if you have any additional questions!
