Remember correct Answers

[bsneider]

• Feature request from a friend who is a user. Remember which questions were correct, and exclude them from subsequent random question batches, as user already knows that rule and wants to learn more without repeatedly seeing the same "random" questions.
• Would require a unique identifier for each question, a hash of question or answer might do, or perhaps just a hardcoded number for each question (simpler). That way we can store the list of ids answered correctly and filter them out for subsequent rounds of quizzes.

I'm not a teacher nor any 'professional pedagogue' but it seems to me that occasionally answering again a question is good to make sure the concept is 100% understood.

Plus with a set of 300ish questions, this issue would be quite secondary?
Maybe it is more problematic on the actual English version that has only 80 questions?
