Here are some courses that were recommended to me by a teacher from One Story.
1. “Your Book Starts Here” an online course taught by Mary Carroll Moore.
2. UCLA Extension has some great online writing classes, as does UC Berkeley.
3. Gotham Writer’s Workshop: C.J. Hauser is recommended for short fiction. If the Master Class is taught by David Yoo, his feedback is great and there’s the advantage of being the only one submitting during one week. It's workshopping without any exercises. With Fiction II, every single exercise led to a story.
4. James Patterson writing classes available via an online venture called MasterClass
