Hey @DIGITAL EXPERT PARDEEP, welcome!
Hmm... I'm afraid we don't have any Youtube growth challenges, but we do have the Newcomer Challenge for Udemy instructors. To better understand what you're looking for: are you planning on becoming an instructor and advertising your course through Youtube?
If so, take a look at our official course on How to Create an Online Course and check our Teaching Center for marketing tips.
I hope this helps!
