I know "exams" sounds kind of scary, but I think by getting tested like how I would if I took a real Korean class in school really helps me maintain the info better! It would be GREAT if Koreanclass101 could function in that way too with the lesson series, like with one long test at the end of the series to test us on all the subject matter covered. Even better if it allows us to have the options of covering combined series like newbie and beginner series or just one series (newbie).
I do like the little tests on each lesson. But I think they could be improved if they included all the vocabulary instead of just 5 vocab words.
