The scores are standardised so that within a month bucket of peers the top scorer will get 140 and the bottom will get 70. If a candidate was the best at both NVR and VR they would score 280.
And for those that go on about "summer babies".... this is irrespective of age. It is possible to score 280 regardless of date of birth. The "summer baby" advantage is an 11+ myth.
100 is average in the bucket with a standard deviation of 15. So if you whip out your normal distribution I think it means that if you score >135 ish then you are in the top 5% ish of the tested candidates (again IRRESPECTIVE of age).
The pass mark is set in order to make the same number of offers as there are places.
The NVR is rock hard; so a good score will need good intelligence, a good undertanding of the question types (via preparation), good technique and an element of luck. It is difficult to cover all the questions in the alloted time.
Also... remember the average 100 is based on the group being tested. It is a self-selecting group comprising many smart and extremely well prepared candidates.
Thanks for the infromation it makes it all crystal clear now.
Yes NVRis a subject the child need to be rock hard to understand it and needs to do lots of practice to stand any chance of passing these exams, as they have to answer the questions within 30 sec, so they have to be well prepard either at home or outsidefor these exams.
More and more candidates are sitting for these exams not sure what the ratio is for getting a place in these schools 1 to 10?
