You will need to setup a subscription for Theory Test, the standard subscription tier allows for 10 concurrent pupils to use this feature.
Below the other tiers can be seen if you need to add more pupils, this information is available on the Web Admin www.totaldrive.app
Once subscribed, go to the "Manage Users".
Here you can add and remove access from your pupils, e.g. a pupil passes their theory test and you want to allocate the ability to use this feature to another pupil. You can view pupils in the Active list, Waiting List and Enabled list. There are also buttons at the bottom should you wish to make sudden changes to all pupils.
