Re: TOEFL-iBT. Is it difficult?
The questions can be from any subject area or about your experiences. Examples for speaking and writing could be:
1. Describe your experience of your first day in high school?
2.
Some people choose friends who are different from themselves. Others choose friends who are similar to themselves. Compare the advantages of having friends who are different from you with the advantages of having friends who are similar to you. Which kind of friend do you prefer for yourself? Why?
3. If you could change one thing about your country, what would it be and why?
4.
Some university students believe that they spend too much time in classes and would prefer to have more time for indipendent study and research. Others prefer to learn in a classroom setting, guided by professor. Which type of learning is more valuable: indipendent study or classroom learning? Why? Include details and examples. Note that there isn't a right or wrong answer as people have different opinions. Just be able to phrase your answers properly and try to give examples to support your answers.
From your writing above, your english is pretty good. You could also try reading out to yourself. I took an English Composition class, and it is amazing how an essay you've written sounds when you read it out loud to yourself.
Also, there are TOEFL prep forums out there. If you do a search on google, you will be able to find some helpful ones.
Goodluck.
