I really like the training here. It was a lot of practice. In the first week, we were able to observe some of the lessons, so it was nice that we could see where we were going to teach, and that we did not start teaching straight away. We started with the 20-minute session. Just practice and see how that went and then afterwards you’re doing the hours and that was really fun. The schools are nice and the children are really nice and friendly. So, for me with no teaching experience, that was a nice way to start. The surrounding of the school is very nice. I’ve been to the national park. The night market is really nice.
