First and foremost, Sabrina and Kira's enthusiasm and charisma! Their way of teaching and interacting with students is really engaging, which I think is the most important thing when learning a language. That's because learning a language requires continuous commitment, so you really need a learning environment which is engaging and enjoyable. Also, it's clear that a lot of thought has been put into designing the course and the content. I like that there is a wider monthly topic with weekly sub-topics. Because the weekly topics all relate to each other, this means you can build up your use of new vocabulary each week, and eventually you become more and more comfortable speaking about the wider topic (eg. social media) . I also appreciate that the classes are short and frequent, which is made possible by being online. I think this kind of routine is really important when learning a language. The classes are both short and digestible, but also rich in content. In the past I have participated in face-to-face courses which consist of one 2.5 hour class per week, and I think the Moonlight way of doing it is much better because your brain retains more information when you are doing a little every day rather than one lump per week. Also, no time wasted travelling to classes!
