I don't know whether they will reject you based on the psychometric test, as it's part general knowledge, part IQ, part personality. But I do know that regardless as to whether you get the job or not you can request a copy or a report on the test from recruitment. They give contact details after the test.
I didn't request a copy after mine, so I don't know the specific details, but I do know they offer the service. I guess it would be handy to have if you make it to the final interview but don't get the position and are still keen to apply later on.
