I need help for billing info

Hello.

I thought it would be a good idea to use AWS Educate for simple learning about AWS.
https://aws.amazon.com/education/awseducate/?nc1=h_ls

The 1-year AWS Free Tier applies when used as described in the document below.
Please note that if you use it in any other way, you will be charged a fee.

Hello, The free tier is only free is your account remains within the usage constraints for eligibility. You can check your status for each service here: https://us-east-1.console.aws.amazon.com/billing/home?region=us-east-1#/freetier
