I would like to know which answers I got wrong on each quiz and to be given the correct answer. In this way I could learn from my mistakes and improve my knowledge. To not know, means I will always get it wrong, unknowingly. To be educational, there needs to be a feedback loop. It would be useful to know the minimum time required to go through each module, in order to gauge the amount of time a person needs to allocate for the course. I found the required minimum time on each lesson frustrating. But, I'm assuming that's a regulation for an online course. So, knowing how much time is required for each module, would be helpful to plan one's time and also set one's expectations.
