After logging in, you can take a Practice Test to try sample questions in the same format as on the full test and have the option of estimating your English proficiency. You will see two options once you press "Practice Test."
For the "Sample Questions" option, you will have the ability to try out questions from the test. You will NOT receive a score estimate at the end.
For the "Get Estimate" option, you will also have the ability to try out questions from the test. You will receive a score estimate at the end - if you have purchased a credit to take the test at any point in time.
Please note that the Practice Test is much shorter than the Certified Test, so the estimated score range given at the end may not accurately measure your proficiency.
