Thanks. I found this useful link thanks to looking up batchim: http://www.koreanwikiproject.com/wiki/Hangeul_step_5. Hope it helps :-)
I have no idea where to leave a comment about the way we are tested so I will just put it here. The way you are testing to up a level is a joke. How can each test be almost exactly the same and be called more difficult than the first test to skip levels? Also, instead of always asking for just an English translation of a particular word, you should flip that and ask for the Korean translation for an English translation.
