Payment is really low (I would love to do this as a full-time profession, but unfortunately can only earn a minimum of around $2 per class.
Getting booked lessons are nearly impossible when you are new on the platform (even when setting your booked fee to the minimum).
Incentives are not easy to get if you are new.
Hopefully the admin at NC would be able to build a fairer system to help new teachers (among the 15 000 existing members) to stand out and succeed.
