Practice makes perfect, so why not try and improve your score on psychometric tests by practicising them a bit more?
You can use our LibraryThing online resource to browse the reference books available to use in the PCC on this topic. Click on Books from my LibraryThing and select the psychometric tests and aptitude tests tags to view the books available.
Just drop-in Monday-Friday 9.30am-4.45pm if you’d like to have a look at these books.
Also, take a look at the sources for practice tests listed on the PCC website at http://www.brunel.ac.uk/services/pcc/students/interviews-and-assessment-centres/psychometric-tests/sources-for-practice-tests. Here you will find samples of verbal and numerical tests and other types of tests such as critical thinking and lateral thinking and situational judgement tests.
