The 120 hour course took me perhaps 25 hours to complete and was largely filler. While some information was helpful, much of it was rushed through. There were about a dozen videos, and two were simply Premier TEFL recruitment advertisements. Most of the others were very low quality. At the end Premier TEFL tries to shoehorn you into buying a copy of your certificate (which you already paid good money for). They also offer letters of recommendation, and teaching opportunities you must pay for. While Premier TEFL is not a scam, it's not much better. Their main interest is getting as much money from you for as little content as possible. Getting a TEFL certificate in person is a chore, but it'll actually teach you something in the long run.
