There's a lot of work to be done to make this a passable quiz. I gave up when "hit the nail on the head", "piece of cake" and "kill two birds with one stone" where all incorrect. You need to add a lot of type-ins for slight variations in grammar and for alternative expressions, as some of these are quite vague (e.g. to not feel well). You also have at least one typo (see eye yo eye)
