 Hi, I'm Linda from the Linda Living in China Vlog and I am getting my 120-hour TEFL certificate from ITTT. And I just finished Unit 4, which is a grammar-based unit. It's all about the present tenses. And even though maybe grammar-based units are quite boring, I think they're quite useful because most of the English, like native-speaker English teachers, we use the grammar every day and maybe we don't know what non-native-speakers have problems with, exactly. But the units in the ITTT TEFL course really explain what are the difficulties for non-native-speakers and I think that's a great plus. So I'm looking forward to Unit 5 and I'll keep you updated. Bye-bye!
