So. You are looking for information about the "Test of English as a Foreign Language" (aka TOEFL)?
We have good news and bad news for you.
The good news is: you can find information on TOEFL by going to the Educational Testing Service (http://www.ets.org/toefl/) website. That should get you started.
The bad news is: you may need some work on your test-taking skills. This website, as perhaps you have noticed by now, is about Thermoelectrics and has nothing whatever to do with the TOEFL exams. Even though the spelling (ets.org vs. its.org) is similar, the meaning is entirely different. The context (i.e. the fact that this website is about thermoelectrics, and not testing) might have been a clue for you.
Although you have not had a particularly auspicious start, we wish you the best of luck on your exams.
