Teaching English is an excellent way to make money. There are several ways to do this but it depends on time and resources. Some people prefer teaching in person at a language center. Others offer private lessons and teach one-on-one. But one of the easiest and most profitable ways is to work online (via Teach Away).
Remote teaching is very easy because the websites provide the content and curriculum. Many students come from China and other Asian nations where there is high demand. The time difference also makes this great for part-time work because many students will want to study during U.S. nighttime hours.
