All new subscriptions are on game mode by default, and this means that you have to complete the first lesson to unlock the second, and the second to unlock the third, and so on.
Game mode is particularly useful to students, but teachers may want it turned off in order to grant them unhindered access to lessons. To prevent abuse of the platform, only users on a monthly subscription plan or higher can deactivate it.
For help regarding this, please contact us on any of our helplines.
