generally nice flashcrads. I would just recommend not to use too long text but rather organise the answer then in bulletpoints. I would also not ask too much in one question but rather separate the question in more subquestions on different cards. That would mean more cards but an esier quicker hence more effective way of learning. most cards are good!
