A Good Course to Introduce or Refresh TESOL Knowledge

I studied TESOL for a year in University and looking to refresh my skills and get accredited so I could teach abroad, I took this course. A lot of the material was similar to what I'd experienced in my University course, with some areas getting more attention, such as teaching young learners specifically, which is what I am looking to do when teaching abroad.

The course includes regular tests to solidify knowledge, and at the end of the course has a final assessment which will call back your experiences on previous tests.
