Waaaay too much time. Taking my time plus I'm on my phone which only allows for one finger typing and I still had well over a minute left. Too easy with this much time IMO.
You should do the quiz = 'Two Letter US State Abbreviations' which gives you 60 seconds for the same quiz. This quiz is for those of us that are not the fastest typists in the world but still like to finish a quiz for the sake of knowledge and learning. IMO Not every quiz should be a typing competition.
