How long after failing Subject 3 can you schedule the next attempt?

[AuroraAnn]

You can schedule it after a certain period. If you successfully book a driving test but fail to attend on time, your test result will be recorded as a fail, and you must wait 20 days before rescheduling. If you cannot attend the test due to unforeseen circumstances, you must cancel the appointment in advance: Due to upgrades in the driving management system, starting from June 1, 2012, according to Article 46 of Chapter 6 in the Ministry of Public Security's 'Motor Vehicle Driver's License Business Work Standards', which states 'if an applicant fails to attend the test at the scheduled time, the test result will be recorded as a fail,' candidates who cannot attend the Subject 2 or Subject 3 test at the scheduled time must have their driving school submit a written application to the respective subject supervisor at least 2 days in advance to cancel the test. If neither a written application is submitted nor the test is attended on time, the test result will be recorded as a fail, and you must wait 20 days before rescheduling.
