There is no option right now for you to reset your account. While you can practice our questions as many times as you want, or watch the videos any number of times, there is no way to reset your account or clear your performance history manually.
However, we can reset your account for you, if there is any technical issue at our end which affected your tests or performance or any account data. In all other cases, we do not reset accounts.
If you need any help with resetting your account, let us know by messaging us through chat.
