January 2015 SAT Sunday

I had 4 math sections so obviously 1 was the experimental. 3 of the sections were routine, just like all my practice testing. 1 section was bizzarre and different so I assumed it was the experimental. However, in searching this site it looks like this was the June 2010 test and what i thought was experimental, was a real section in June 2010. My friends agreed with me that this weird section must have been experimental but is that possible if it was a real section in June 2010?
