Just picture yourself in a work environment and imagine what kind of employees they would want. Don't picture yourself in a school environment because school and work are two completely different situations. You have to be consistent with your answers- they'll ask you a couple of questions multiple ways. For example "Are you a reliable person?" and then 10 questions later: "Can your co-workers depend on you?" Make sure you're always putting the same answer. Sometimes they'll switch questions around to try to trick you or throw in one word that throws it off.
You just have to read carefully and really try to understand what the question is saying. What you think it might mean at first could really be interpreted another way. I've heard it's good to put down a lot of "strongly agree" or "strongly disagree" as opposed to selecting "neutral" too many times. Also, don't let the timer run out on too many questions. I ran out of time for only one and was okay, but I don't know how many is too much so I wouldn't risk just not putting down an answer.
took on for TWA years ago. Didn't pass, later after they dropped the test I got hired. LOL!
