Each mock is normally designed for single use within the season. This is because the UCAT is built around unseen questions, and repeating a mock you remember, even partly, can make the experience feel less realistic and give you a less accurate sense of your progress.
That said, if a good amount of time has passed since you completed a mock or there are other extenuating circumstances and you feel a reset would genuinely help, we can look at this on a case-by-case basis. Just let us know which mock you’d like to reset and when you last completed it, and we’ll be happy to review it for you.
It is not possible to reset the question bank, but once you've completed all the questions in a section they will automatically start to recycle.
