Your results are classified as being in one of 4 bands; i.e. Band 1 to Band 4, with Band 1 being the highest.
If your results are valid for 3 years then you've scored on the better end of the scale, and therefore should be more competitive in that regard. Bearing in mind of course that it is not only your test results that will factor in to your competitiveness.
Whilst I'm not sure at what percentage (or what ever measurement is used) the bands cut off, if you're curious to find out which band you've fallen into you can ask the psych on assessment day and they should be more than happy to tell you.
