I'm sure this has been asked before, but I can't find an easy solution.
I don't really want to study a book. I just want a big list of characters thrown at me at random.
I feel that if I study from several book-based lists, there is some doubling up, and some dross (names, etc) to gradually filter through. Using this method also tends to be dominated by simple characters and it isn't comprehensive.
Is there a way to do this?
