To add as its mentioned here- Azure for Students
Azure for Students offers a credit to eligible users to use Azure services. These credits are limited to $100 and must be used within a 12-month period. It's important to note that any credits left unused at the end of a month will expire and cannot be carried over to the next month or transferred to other Azure subscriptions. If you exhaust your credits, your access to Azure services will be temporarily disabled.
To continue using Azure, you can switch to a Pay-As-You-Go subscription by contacting Azure Support.
This upgrade allows you to keep using Azure without interruption, but you'll be billed based on your actual usage.
Please let us know if you have further query on this.
