If I don't remember a word I will hit show on the first character and usually once I see the first character I remember the rest. Now I will mark the first character wrong. But a lot of the time I know the character I marked wrong, but just didn't remember that it was the first character in the word.
Sometimes I will do the same thing if I can't remember the first and second character but remember the last, so I'll mark the first two wrong, even if I know the characters themselves, because I didn't know that they were the first two in the word.
But now that I know the system a little more I'm not sure if this is such a good thing. I mean if I marked the character correct because I know it individually maybe that might not be the best time whether or not to make a judgment on if I would have got it by itself since I just saw it and that could color my perception, so I see that as a problem with marking the character right but the entire word wrong. Has this hurt me? Or is it okay?
