I found the courses interactive! Better than using Duolingo for the first month as this helps me to build a base and interest in learning the language. But I kind of get to a plateau after finishing level 2, so I go to do the travelogue, which is quite fun. Though at the first half of travelogue, I found the story plot is like kind of missing something, luckily the later part improves a lot with more conversation. But it is frustrating that there isn't a all-merge dialogue that includes all the audios from previous lessons, like the review audio in level 1,2,3. So basically I can't go hand-free to listen back the dialogues that I have gone through while I am cooking, running ...etc. And the updated version of level 1,2,3 is putting away something I found very nice - that’s having the conversion dialogue at the end of the same lesson page, instead of putting them at the “all conversation” part. Hope these features can be added and improved. Thanks!
