When can I receive SMS notification at the latest for the subject 3 exam?

If the reservation is successful, you can print the reservation voucher on the business completion page; Generally, you will receive SMS about one week before the exam (individual users may not receive it because of the network and other reasons).

In addition, you can refer to the Announcement of Driver Test Appointment Results on the appointment website. If your appointment date has been announced, you can click "Details" and the page will display the sorting results. You can confirm your reservation result and serial number according to the sorting time, last name and the first 6 and last 4 digits of your ID card.
