Though I participated TOEFL® Test Preparation: The Insider’s Guide on edX TOEFL course and The Complete TOEFL iBT Success Course (NEW VERSION) on Udemy, there are not so many practices than I expected. I googled some free practice questions online and am going answer then after the courses.
Official Practice (TOEFL Practice Questions)
I did not know that TOEFL releases free test practice materials. I expected it grades as well, but unfortunately, it presents sample answers only.
If we buy practice tests, it will grade within a day. Though it is not inexpensive, I am wondering if I take it or not.
Barron’s Online Practice
Barron’s is a famous publisher to study for the exam. This site shows amount of practice tests for free too. Actually, I have a paperbacked version of 16th edition for TOEFL iBT prep book. The first reading material is the same with on the site and in the book.
I can use google dictionary when I visit the site and it is a good ladder to get familiar with passages similar with the real tests.
