Some of the questions were ridicolous like, how long would it take to cool a cup of coffee in a vacuum. When would you ever need to know this!!

I have absolutely no idea how to solve that problem
now, but it seems like the type of question that would have been relatively easy when I was taking 1st year chemistry. I guess you'd use basic thermodynamics or Newton's Law of Cooling or something else that I no longer remember from my undergraduate days (Boyle's Law is popping into my head, but I think that applies to gases, not liquids). I assume you were supplied with the the volume of the coffee and the surface area of the mug, as those would be necessary to calculate the cooling time (cooling will be faster with smaller volumes and greater surface areas and slower for the opposite).
As for "when you would ever need to know this": anyone who has that attitude (and MANY people do), is missing the entire point of a university education. If you only want practical job training, go to a technical/vocational school like SAIT. Universities exist to provide a well-rounded education, not to act as workplace training facilities.

No this is how crazy the tests were, another one was how much heat would be lost in x amount of time if a portion of the airplane cabin ripped off mid flight.

What's so crazy about that question?
