AWS solution student charging

Hello.

If you have already opened an AWS account and have been charged unexpected charges, you can file a dispute with AWS Support.
https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/checklistforunwantedcharges.html

For questions about your AWS bills or to appeal your charges, contact AWS Support to address your inquiries immediately. To get help, see Getting help with AWS Billing. To understand your bills page contents, see Using the Bills page to understand your monthly charges and invoice.

Therefore, I recommend that you open a case with AWS Support under "Account and billing" and inquire.
Inquiries under "Account and billing" can be made free of charge.

If students are learning about AWS, I think they can use it for free.
