1. The banking system is congested and the online payment service is open 24 hours a day. In order to ensure the success of one-time payment, candidates should avoid the payment peak from 9: 00 to 17: 00 for payment procedures.
2. The account balance is insufficient. In addition to the fees required for registration, there must be at least 1 yuan in the account to ensure successful payment.
3. In some places, online registration is required, and online payment can only be made after on-site confirmation at the designated place.
4. Because there are many uncertainties in the public network, candidates are advised to use computers in public places such as Internet cafes. After completing registration and payment, they must quit the relevant registration and payment system to ensure that their information is not kept on the computer.
