The previous posts are correct in that there isn't much you can do to prepare. I would have a look at the skytest website about this disc. The screenshots and descriptions are accurate compared to what you will face at stage 2. I don't think it's worth buying as it's expensive and it all is to do with how you perform on the day. The pressure and stress you are under whilst taking the tests will be different to at home. More cubes and more maths involved but not in great detail. I would concentrate on your degree in case this doesn't work out. All the best for both though.
