My Upcoming TOEFL iBT

I bought this book yesterday from the nearest bookstore because I must follow the test on July 25.

My God, this book is so damn heavy and thick.
I admit that this book give us a lot of explanation, strategy and tips on how should we earn a higher score.

Unfortunately, it is absolutely not practical.
I prefer taking TOEFL pretest as it is available on ETS site.
I can take the test as it is installed in my laptop and then surf and click.

I will update my information regarding this IBT test later
