Also, repeating the missed word is fine, but I think it would be better if how you studied that word varied more. So instead of always having to select the translation after seeing the characters, maybe type the english definition once, select the correct pinyin from a list once, write the correct pinyin, fill in a sentence with the word, show the english and have to select the correct character (I don't think this happens at all in the reviews. I might need to check my settings...)
