Return to the Test Directory page and choose the "Products" link at the top. This will take you to the Products Directory page. On the left side of this page, choose "Resources for Test Takers." Then, at the Resources page, click the link for "Preparing."
Find the heading "Assessing English as a Second Language," and choose the link for "TOEFL ITP Test Preparation Products."
Go to the TOEFL Institutional Testing Program page. Decide whether you want one of the paper-based guides, "TOEFL Sample Test 6th Edition," or "TOEFL Test Preparation Kit, 2nd Edition." These guides offer hundreds of practice questions that generally appear on the test. Choose one of the links to place your order on the ETS website with a credit card.
Select the "Store" link at the top of the TOEFL Institutional Testing Program page if you'd rather get the guide for the online test.
