I doubt very much Paperclips got through stage 1 by wild guessing! A lot of hard work and preparation would have gone into Paperclips application process considering stage 3 has been passed.
You could wild guess if you like but it'll get you one place only...straight to the middle of nowhere! (Unless you're very lucky and have actually managed to select all the correct answers - doubt it muchly!). I would hate to think of people applying that logic to controlling aircraft - would certainly put me off flying for good if they did!
Being accurate and getting the answers correct is the way to go...just do so with a bit of speed. Honestly, stage 1 is nothing to worry about if you have the aptitude for it. You are given all the examples of tests that you need in the stage 1 info.
Good luck!
