Tucked away on the web site of England's Chartered Institute of Taxation is a section on IQ tests.
The tax body says there are a number of tests to be found on the web, and has picked out three which provide a score for you on-line.
It does point out that the Institute has no control over external sites and it cannot take any responsibility for any aspect of those sites. So don't blame the CIOT if the results are not what you expected!
Why not have a go, and don't get depressed!
Such tests are an ideal warm up exercise before an interview in order to prepare yourself for those difficult questions.
