What makes making money as an online English teacher particularly interesting and easy with sites like VIPKID is the fact that you don’t have to spend any time or money trying to find paying clients. VIPKID is a huge platform with hundreds of thousands of paying students. The site takes care of everything for you. Bringing you students, scheduling classes, pay, etc. All you have to do is set up your own schedule (yes, you get to decide when you want to work!) and teach during those hours.
You can pick writing jobs directly from a live job board or have to bid on a job and hope that the job is awarded to you by the relevant client, depending on how the site works. Some sites may require you to take an English grammar and writing test and some may require you to submit a sample or samples of your work while others may require you to take a grammar test to evaluate your skills. If you pass any relevant test, the relevant site will let you take on writing jobs.
