Hi there!

Thank you for reaching out. It is currently not possible to check the difficulty level of each question after the test is completed. However, you can still review your practice tests and have a better understanding of potential areas of improvement.  

Scroll up on the left side menu in the Practice tab to locate past tasks and tests. When you find the relevant practice to review, click on it, and then select the "review" button as shown in the images below.
