For those with a widespread certification need and for polyglots in the making, it is entirely possible to have several different test preparations at the same time.
GlobalExam does not limit the number of subscriptions you can have simultaneously. On the contrary, we encourage our users to complete as many certifications as possible so that their language skills can continue to improve!
An example to help you understand:
You can purchase a quarterly subscription for the HSK and subscribe to a one-week subscription for the TOEIC. During this week, you will have access to all the TOEIC content and HSK content on the platform.
