Before you decide to buy a TOEFL practice test from ScoreNexus, you can sign up to take a free test.
✓Sign up at scorenexus.com/free-toefl-test.
✓This free practice test has the same four sections as the real TOEFL, but each section is much shorter than a full test.
✓When you finish, you can see a Score Report (but a short one). Also, the Speaking and Writing sections will not be graded–instead you can see Suggested Possible Answers.
