How to choose a TOEFL mock test for the 2026 TOEFL iBT
This article is written by Unlock Prep, which sells TOEFL mock tests. Unlock Prep products appear in the article.
Choose a TOEFL mock test on five criteria: the 2026 update, on-screen timing, scoring and feedback, weakness diagnosis, and a published price. Start with ETS's TOEFL TestReady and Practice Test, then practice with Unlock Prep's 15 TOEFL mock tests, built by Hyukjoon Kwon, Lead TOEFL Instructor at Pagoda Academy, and Robson (Park Taehwan), Lead TOEFL Instructor at YBM Gangnam.
Five criteria
When you choose a TOEFL mock test, check five things: whether it follows the task structure of the January 2026 update, whether you take it on screen under time limits, whether you get scoring and feedback, whether it diagnoses weak areas, and whether the price is published.
The updated test has three Reading tasks, four Listening tasks, three Writing tasks, and two Speaking tasks. If you practice only with items in the old format, you will not meet the new tasks before test day.
Practice materials from ETS
The ETS preparation page describes TOEFL TestReady as a personalized, one-stop TOEFL iBT prep portal with practice tests, courses, guides, books, performance insights, and progress tracking.
TOEFL iBT Practice Test 1, a PDF published by ETS, says it aligns with TOEFL iBT tests from January 21, 2026. It also says it is not an exact replica of the actual test, because directions and questions were adapted for paper format.
These materials come from the organization that makes the test, so look at them first when you are learning the new task formats. Please check access terms and prices directly with ETS.

Unlock Prep's TOEFL mock tests are online full-length practice tests built on the task structure of the TOEFL iBT updated in January 2026. Rounds 1 to 10 are medium difficulty, and rounds 11 to 15 are high difficulty and reflect recent trends.
You work through each section on a screen with a running timer, and AI reviews Writing responses on each task's scoring axes, showing sentence by sentence what to fix now and what to do next. Missed questions and lost points feed into weakness practice, so you practice your weakest types first and check again with a new diagnostic.
Mock test scores are estimates for reference, calculated to reflect ETS scoring criteria, and may differ from your actual test scores. You can start for free when you sign up, and the Basic plan costs KRW 49,000 for one month.
