You can suspend your membership for free for 3 months. After that, to extend your suspended membership, you will need to rejoin for one month. This will keep your data alive on our system for another 3 months, and prevent you losing access to the lessons that are already unlocked for you.
This is because it costs money each month to keep your student account open, and to continue to store your assignments and data on our system. From time to time we may need to make space available on our servers for our new students.
Please note that when you rejoin, you will rejoin at the current membership rate for new members. It is not technical possible to guarantee that the monthly amount will be the same as you are paying now. Also, you will lose your free monthly eBook for the period that you are suspended.
