it would really be an improvement with the quizzes if one could get your answers after the quiz it scored. That way one can learn from one's mistakes!
Hi! You might want to move this to the General forum, rather than the Spanish forum. :)
But once the answers are available to the public the test is no longer valid. It is a tool for evaluation, not teaching.
It's easy to get around that by telling the test taker what category area they missed questions in. It wouldn't be hard to say that you missed one question in conjugation, another question in future tense and one in listening comprehension.
