It is indeed a big deal to have additional certificate in ESL- TEFL in an affordable but highly qualified and in an accessible way. Studying and learning and working at the same time isn´t easy. There were many times that I don´t feel like doing it but with the support of the management of SERIOUS TEFL I was able to cope up with the study modules despite of my busy schedule and activities in school. I would like to encourage everyone to register on this site for educational learning experience.
