I've finished my C1 Morning Course (Dublin) in MixTree and I'm completely happy with the whole experience! We practiced a lot of speaking in every class, and it made me very talkative :) I love the communicative approach of teaching with flipped classroom — you're always working with your classmates and learning new grammar or vocabulary together! My teachers, Magui and Kathleen, are amazing people. I've also decided to continue with the next part of this course in October!
