User Reviews

I finished all of Book 1 and Book 2 (the beginner books). I am really grateful that an app like this exists for free that teaches grammar. However there are a lot of typos and switched content. I started to lose faith that the information was correct. In book 2 chapter 16, 17, and 18. All have English typos. This reminded me that I saw typos before in book 1 but ignored it because English is probably not their first language and it wasn’t that bad. Then I started noticing the Korean mistakes. The grammar definition for 에게로 was wrong. The Korean example sentences for some of the grammar were switched while the English translation was correct. When it comes to educational content, it should be triple checked to make sure vulnerable leaners are not confused or lead astray. This content seems like someone pasted it in and never checked if it was correct. So I cant keep using this service since I’ve noticed so many errors in the content.

어플을 너무 잘 사용하고 있는 팬입니다. 지난주쯤 부터 아이패드로 어플을 사용할 때 어휘 부분에서 단어가 제대로 안 보이는 현상이 일어나고 있습니다. 제 기기의 문제일까 다양한 시도로 고쳐보려 노력했는데 단어카드들이 짤려서 단어가 안 보이는 현상이 고쳐지질 않습니다. 세종학당 측에서도 확인 부탁드립니다.
