The pass mark for the 11+ in Buckinghamshire is 121. This score is calculated based on a childs performance against all other pupils sitting the test, which means that the pass mark is different every year. Although the percentage of questions pupils need to answer correctly to achieve 121 varies greatly per year, it is generally accepted that a child will need to get between 75-85% of the questions correct in order to achieve a score above 121 and be able to apply for a place at a grammar school in Buckinghamshire.
