OHSAA certification

[uxley11]

I live in Pickerington and work for the PYAA. So i will be in the central district. I had another question if you or anyone else could answer. I will be taking 8 two hour sessions. Do they generally go over 2 hours and is that extra time counted towards the 25 hours? Also, will the test take another 2 hours, or will you take that on the eight and final class? I don't plan on being a varsity umpire until I am in college at least. and I want the minimum hours so I can make an extra $25 a game. I am just confused, because 8x2=16. Plus the 6 hour mechanics session equals 22. So where do I get the other 3 hours if I don't have to do the baseball scrimmage. Thanks for any help.
