While quickly going through the questions, be careful not to exit the section. ETS’s UI does not display any confirmation pop-up when you leave a section. Once you exit, you cannot go back.
The “Next” and “Continue” buttons are in the same position on different pages — one before and one after the section ends. Be cautious when switching between questions. Don’t try to swap too quickly; you might accidentally enter the next section.
I believe ETS has deliberately kept the UI unchanged. How hard would it be to add a simple confirmation pop-up to warn users they’re leaving a section? It’s really frustrating to shuffle through the questions — especially in the verbal section.
