Apart from the spelling differences you can see those by clicking on the USA - UK differences at the left hand side of this page - there are a number of differences in vocabulary listed below.
I suggest you look them over because you never know when you may run into an American after studying British English, or when you may run into a Brit after having studied American English.
Having been to England a number of times now myself, I can assure you that the difference between American and British vocabulary are just enough to cause a few laughs.
Well, maybe a few... misunderstandings. ;-)
What's important to remember?
That both British English and American English are accepted on the examinations as long as you consistently use either one or the other. In other words, don't mix!
