Hi, I love memrise and have, like everyone else, already improved my Chinese a lot which is great since I am going to study for real soon. A great confidence booster! I was wondering though, I started the mandarin survival study and HSK 1, and afterwards noticed that memrise also had courses made from the books my Uni uses. Now, I would like to combine them, that is, study both the vocab in the Uni books and the mandarin survival (as I would like to have a sturdier base and the first two courses are really well set up!), but I was wondering if memrise automatically eliminates double words/characters from my gardens? So, if I have already planted and harvested i.e. 你好 in one garden, will I have to learn the same words again in another?
