The only change here for the 2012 syllabus is that A minor is no longer required, and that the option of natural minor scales is included.
These diagrams only show the harmonic minor pattern, which I believe to be by far the most commonly-played in exams. If there's any demand for it, though, I'll modify it to include the others.
Edit: for those who want note names on the diagrams, you can use the relevant pages from here.
Also, courtesy of Degzi, is a sheet of all the scales (including A minor) ready to cut up into flash cards - ideal for when you've got them all pretty much learnt, so that you can practice playing them in random orders just as you'll need to in the exam.
