TESOL program

I have always wanted to have my TESOL certificate, as I have always wanted to teach English. Initially, I was going to pursue my master's degree in TESOL here in Korea, as my university is one of the best programs to teach it (Hanguk University of Foreign Studies, HUFS). However, when I went to a trial class, I was shocked to see that they taught the course in FULL Korean, which I am not fluent in as I was born and raised in another country. Years later, after graduation and having a teaching job, I decided to have a certificate that would allow me to have a solid teaching background, TESOL, so I started to look online for courses in English for me to study with more ease. I found World Tesol Academy, so I enrolled. Luckily, there was a full certificate package with a discount, so I am currently studying to get my other certificates: TEAL, TEYL, and TEOL. Wish me luck!
