No- I know that there is no -ve marking. I'm saying do HR analyse the way in which the applicant approached the tests/what they decided was important for a result.
This is the first time they see how you react in a relatively stressful and time-demanding situation... And are likely to see a bit of your TRUE personality in your approach. Seeing as they delegate part of the day to personality questionnaires
I would be surprised if they do not look at HOW you answered the brain tests!
For instance, candidate A scored a better score but I think we would all chose candidate B as a more suitable candidate.
So from a HR perspective should you guess the remaining questions in order to have a chance to pick up a few points, or is it better to do the best from what you attempted and get a higher relative percentage?
