In sports terms, to pull a 360 means to completely turn the team around. Example: the Florida Marlins pulled a 360 by going from first to worst in a year. Besides more people understand a 360 than a 180. I guess you aren't into sports.
You can use 360 in two ways. First of all, you can use it when thinking 360 means turning it around. The second way is if you mathematically look at it, it is still in the same direction after completed. I think he meant it the first way.
Okay Kings Fan. It is a 180. Not a 360. If you turn a team around from bad to good that is a 180. A 360 would be (bad to good and back to bad). That is 360. I hoped I helped you out. Now maybe you could apply that to school.
