The title asks specifically for a programming course but the post text says not to limit to programming courses. It's a little confusing.

Programming is something you will get better at as you do it, so I wouldn't worry too much about it. Instead I would look for computer science courses that interest you and a course outside of comp sci that requires a lot of writing. Although technical writing is probably what you will be mostly doing, consider taking a creative writing or a critical reading course.
