Paying for Premium membership

I have subscribed for the premium membership recently, so i have paid 10 $. Eventually I noticed that subscription will renew every month. How can I stop renewing, because now I want study only for 1 month. Thanks.

If you go to the Account page, you can click the “Downgrade” button to switch back to Free membership. If you prefer to cancel your account, you can do so at the bottom of the Account page but you will then lose all of your data.

Thank you for the information
