Thank you for your inquiry. If you want to gauge your knowledge on the different domains first, you can opt to do the section-based tests first. If you want the ability to view the answers as you go through each question then the Review Mode would be more suitable.
Just a note as well that the questions in the Timed Mode can also be found in all the other training modes and are just presented in a different format.
