This online TEFL course was very well structured. It wasn't only great for teaching but also to renew some grammar and language theory for oneself. I learned a lot of new teaching techniques that I am excited to apply in the future. Explanations and examples were provided appropriately for each of the sections. I did not really need it because the course is designed pretty self explanatory but there would have been assistance from the company any time. Overall, a great and absolutely managable challenge if you are committed to become a foreign language teacher.
