Pros
Very flexible schedule (you create your own), can easily cancel classes without too much of a penalty (make every student that you like a "regular" student so that if you get penalized...only regulars can book you...you have a huge pool of regulars), Cambly provides lessons, you can use almost any website as long as you don't need to share login information, it's fun and easy, many students become like friends, you can learn about different countries, cultures, and languages
Cons
The pay. It has never increased in the 14 years that Cambly has been in business. They are starting to offer a new program called "Cambly Pro" where you can make $15 an hour, but you have to apply to be a tutor for it and you could be denied. You have to have a 99% rating for 3 months to even be considered. If, like me, you are open to all students (and not just your regular students that you have become friends with), your rating can vary widely. No matter how good of a tutor you are, you will not be everyone's cup of tea. Also, Cambly does not allow tutors to teach in some states in the U.S. due to labor laws.
