If you want to score high just answer the questions as fast as possible. Right or wrong doesn't matter. Took it a few times to check it. First time I took it like I should and got 145. Second time I raced through giving same answers got 147. Third time I raced through giving all wrong answers and got 149. So giving all wrong answers fast means you have a higher IQ than answering them slightly slower but correctly. Get real.
Updating my review after the liar that responded from the site said I took it elsewhere. Added the email I got.
Your original test with a score of 145 seems perfectly legitimate.
But if you gave all wrong answers, it wouldn't matter how quickly you did the test, you would not get a score of 149.
You were not provided with the answers, so you don't know which answers you got right on any of your tests.
Correct answers are more important than the time.
