You can work at your own pace

The best words that describes UNI-Prep TESOL: it has a user friendly web page, it is simple to cover, you can access it anytime, and you can fit it in your schedule. I enjoyed and finished it in a very short time. The materials are organized well. When i finish it, i fell myself confident to teach English to non-native students. It gained me a lot.
I recommend UNI-Prep to anyone who needs a TESOL certificate.
