Starting in the 3rd quarter of 2008, there will be a new research format in the simulations. A tutorial will be available at cpaexam.org sometime in the 2nd quarter of 2008. Supposedly the new format will make it more simple to navigate. Personally, I don't think it would take much to improve the current interface. It's cumbersome and you have to hold your mouth just right and say a prayer to get your answers to transfer from the authoritative literature section.
I learned the hard way that you can't transfer an answer unless you SPLIT THE SCREENS. Of course it says this in the instructions, but I have better things to do during the exam than read instructions. 🙂
Here is the link. It's a Powerpoint presentation.
