Even though the exam was created, and is administered, by an American institution — it is understood that the people taking the exam will be from all over the world — and most will probably have been taught British English. So it is not necessary to use American English when taking the TOEFL iBT Exam.
However — it has been stated in almost every text-book about the exam, that: if a person uses either British or American English — they should remain consistent throughout the exam. I can comprehend why they would say such a thing — but it is actually quite ridiculous. Because:
You already have enough to worry about when Preparing For The TOEFL Exam — without having to worry about whether-or-not you are remaining consistent with your use of British or American English throughout The TOEFL Exam. And to be able to do such a thing (according to what the other text-books say), you would have to learn both forms of English… Which is ridiculous.
This is because — when a person learns English — he or she learns certain words which represent certain things. A person doesn’t call a “Truck” a “Lorry” (or vice versa) in one sentence, and then switch to the other word in a different sentence. They learn one word for it — and that is usually the word they will probably use, forever.
The same is true for spelling. When a person learns how to spell a word — that is the way that person will spell it for, probably, the rest of his or her life.
So — RELAX!!! If you see the warning about this on any blog or website — or printed in a text-book somewhere — simply disregard it. It is just another way of causing you undue stress which you do NOT need when preparing for The TOEFL Exam.
. The actual “problem” that these types of warnings are referring to, is already taken-care-of by the very nature of how humans actually & naturally learn — (not by the way the text-books “teach”). The “problem” is “fixed” without you even having to do a thing… So you’re covered. 😉
