This is a Self-Referential Aptitude Test, developed by James Propp, at UMass-Lowell.
If you think something is wrong, take it up with him.
Each question refers to one or more answers on a different question.
You should open a separate document to take notes on your process of elimination.
Consider not starting the quiz until you have all of the answers.
Oh my god. An hour and a half (yes, I'm sorry, I cheated and wrote down what I had and refreshed the page to get full time again) and two pieces of paper later, I did it! I have never been more proud of finishing a JetPunk quiz, and this is without a doubt my favorite quiz on this website. Kudos to you, mightythor, that was awesome!
After many hours spread across two days and multiple excel sheets, I got all but two answers right (Q3 and Q5). I knew something was off, but I couldn't find the mistake until I looked at the answers. Now I'm angry at myself, because I had the wrong number of vowel-answers in mind due to an earlier draft and this confused me. Otherwise, I'd most probably would have gotten it. Still, it was very interesting and you have a nomination from me.
#5 and #20 can be answered without looking at any other question.
#8 can be answered by looking at #7.
With what you know now, you can eliminate answers in #3 and #4.
After that, you can answer #1, #3, and #4.
This will allow you to eliminate answers from other questions.
Looking at #10 and #16 will give you the answers to both.
Looking at #6 and #17 will allow you to eliminate answers from each.
If you look at one of the questions you already answered, it will tell you #12 and #15.
And now you can answer #13, which allows you to eliminate answers from several questions.
By process of elimination you can arrive at #9.
You should be able to answer #2 now, and several others.
Now #11.
#14, #18, and #19 are left. Use elimination for these, answering 18 first.
If I could set the time to a week, I would.
with the hints, shortening the time would be a good balance
