It is not necessary to pay by credit card for the GMAT exam. You can pay by other methods on third-party websites.

1. The GMAT exam fee cannot be paid in RMB. It can only be paid with a dual-currency credit card. Unless you are not on the official website, but on a third-party website, you can use Alipay. These payments are risky, so it is recommended to pay on the official website.

2. The first step to register for GMAT is through the etest website. Log in to the website to register as a candidate. To obtain GMATID, candidates need to provide basic personal information such as: name, mailing address, phone number and email address. After completing this step, the website will display a prompt message asking candidates to wait for review. During this period, they cannot book the exam or choose other services.

3. The second step of GMAT registration is to complete the payment for the examination fee or other service items through the etest website paid link. When the candidate successfully registers as a website user and obtains a GMAT ID, he or she can log in to the etest website. Click the payment link, log in using the three combined GMATID registered username and birthday information, and start entering the payment process.
