When you start to enrol on a course but do not complete the process (for example: successful payment has not been made), a link is displayed in the Next Steps section on the Homepage so you can resume the enrolment.
An email is also sent to you containing a link so you can continue with the relevant enrolment.
When you click a link to resume an enrolment, you are returned to the stage of the enrolment process you reached (for example: where you have entered your account details but did not provide consent to the use of your data, you will be returned to the Data Protection page).
