A: Hey Sumo-ling,

Please find our answers below.

1. We can create five subschools under one main account. Is that correct?
-> Yes, you are right.

2. Since each subschool will have its own login portal, how about a mobile application? Each subschool has a mobile application? or does the mobile app of the main account show all the subschool?
-> The mobile app would be independent for the specific accounts since each sub-school can have different branding.
-> Through sub school. the users can access the courses which were copied from the main account and created specifically from the sub-school account.

3. Are custom domains available for each subschool? As an example, subschool1.com, or does the subschool use the subdomain of the main account? subschool1.mainaccount.com, for example.
-> Yes, the custom domain can be configured for each sub-school account.

Hope, this helps.
