I've gotten a couple of 24 hour tests - they were released electronically so you are timed from when you choose to start to when you turn it in and both times was graded on how much time it took you - more than 24 hours and you failed. One of them had two puzzle questions and I understood how to one of them in an hour or so but didn't figure out the trick for the other one until I took a shower a couple of days later but since I could only do one of them I immediately just told them I would pass on it.
