When doing the practice tasks in Applications of Integration, I have to get 4 / 4 correct in order to become proficient. Somehow I tend to mess up with at least one of them, usually the first one for each session of these practices I do. If I have done the first one incorrectly, I then have to get all the remaining ones correct, or else I cannot start over again. This means that I would then have to get 7 correct in a row, which is very frustrating. These are difficult tasks, and I would like to bring back the old system where you only have to get 3 or 5 in a row correct, and the practice tasks won't stop until you do. That way, you aren't severely punished by messing up the very first practice task, and instead it motivates you to actually give an effort. As per now, when I mess up the first one, I am so demotivated that I just look up the hints because there's no reason for me to try my best, when I know I've messed the practice session up. This involves tons of clicking and reading, and it just wastes my time and motivation. Bringing back the old system of x-in-a-row with the practice tasks appearing infinitely until you make it, would solve this problem.
