As said above, you can't study for psychometric testing. The questions are designed in such a way that they will get an answer to what they are after by asking you several different questions that apply to the same topic. Unless you are willing (or even able) to go back and change previous answers, you won't fool the test or the reviewers of the test.
Just answer truthfully and you'll be very surprised after you've seen the results, if you are allowed to. The two psychometric tests I've done have hit my personality/beliefs/abilities right on the head...and they STILL hired me!
Management will only use it to weed out sociopaths and possibly determine your career path in the future if the test shows you may excel in a certain situation etc.
