I'm just rewatching the seasons and noticed something in the first two episodes of season 3. Since I'm watching the german subbed version, I'm not sure if it is correct or just a translation error or if this is really possible in US schools.

I also know that "time" is a inconsistent theme in Teen Wolf, so I just have to ask.

Scott said in 3x01 that he already turned 18 and in 3x02 Stiles said, he has not yet turned 17.

Questions:

a) Was the translation correct?

b) Can they still be in the same classes?

C) Allison was a year older than her class mates and turned 17 in season one, Lydia celebrated her 17 birthday in season two, so is Scott older than the others and Stiles younger? Or is the german sub bad? I don't get it.
