If you can’s attend my creative writing class at Brigham Young University, then you can find the lectures for a few years recorded and posted online.
The 2016 lectures were filmed professionally by Earl Cahill.
The 2014 lectures were posted by the BYU English Department.
That said, no class, even the one I teach, can take the place of writing on your own and practicing. That will be the most useful thing to you in your career—practicing lots of styles, lots of writing tools, and lots of types of stories. Your job is to learn for yourself what works for you, and develop your own mix of strategies—writing methods, outlining methods, viewpoint/tense decisions, prose decisions—that help you consistently create great books.
