Hi @martinmcbride Udemy policy has restrictions around duplicate content and we've also found that courses with a substantial amount of overlap create a lot of dissatisfaction amongst students. It can be difficult to find the right course when many feature identical content.
To preserve the marketplace experience and ensure student satisfaction, we recommend at least half of every course must be totally original to that course. The less overlap between your classes, the better. Please use your best judgment to deliver a unique, valuable course that will teach students something new. If you still have specific questions about this, please send an email to our Trust & Safety team at policy@udemy.com
