Here is what one Test Taker wrote on his blog about his TOEFL experience:

“I took TOEFL exam 10 days ago. I felt that practise is very important on every single part of the test. For example, Reading, Listening, Speaking and Writing. When I was doing sample test I feel that the time is very sufficient for me, because I always finished my test ahead of time. But the real exam was different. I hardly could not finish my tests on reading and listening. The reason is that I did not want to do wrong on the real test. I was more seriouser and spent more longer time on real test than sample test. I did not get my score yet, but I hope I will get a higher score.

What I am going to is please start your preperation earlier. Please do more practice on sample test, every part of the test. Then you will be more confident x, and you will be able to control your time more efficiently when you take the real test.”
