Some of the tests they don't show the actual scores, such as shape recognition and hands etc. Also be aware that it's also based on how quickly you answer, they say in some situations it's better to give an incorrect answer within a couple of seconds than the incorrect one within 30 seconds. I know this is the case with the hands, you should be aiming to answer them all within the first 2-3 seconds and the time steps shouldn't make a difference. If you got near full marks on all the others I can only say that these were the 2 you perhaps slipped up.
