We compared 15 Collections courses currently listed on Udemy, priced from $19.99 to $199.99.

How these 15 courses were chosen
Every course below is a real, currently listed course from Udemy, matched to "collections" by our catalog and ordered by our CourseAsk score. Courses whose own title names the topic rank above those only tagged with it.
There are no star ratings on this page — the course feeds we license do not include them, and we would rather leave a column out than fill it with a number we cannot stand behind. What we do have is price: these range from $19.99 to $199.99, as listed by the provider when we last updated the page.
