displaying data in descending order (automatically)

Hi Guys,

I have a table with exam results in it, Column A has the name of the student, Column B has their overall score:

I.e.


A B
John 94%
Billy 72%
Frank 100%
Mary 82%

Is there a way to have an area of the sheet/a new sheet automatically display the list of results with column B in descending order? (and update when the scores change?)

Thanks,
