Are there any changes to DAT Math since 2008?

I took the DAT in 2008, and I am retaking it next month. Are there any changes to the DAT math section since then? I know a calculator is now available to use. Should I change the way I study (with or without a calculator)? Are the problems harder since I can use a calculator? I am using KBB and Math Destroyer.

Thanks!
