What is the difference between the 2007 dressage test intro B and the 2008 test intro B?

tkt117 asked:

Obviously I am new to dressage. My horse has schooled and competed to level 2-3. But I want to do a dressage schooling show in October. I see that I can buy the tests for $25 online, but when I watch You Tube it looks like there is no difference between 2007 and 2008 tests. (At least for the Intro Level B test). Does anyone know? Thanks!
