You can do nothing with this without any addon. I have tested it.
It is practically useless. I have downloaded version 7.5 from somewhere else and tested it. It worked but not many options as they sell all important options as add-on modules. I am giving you my downloaded one but believe me it's useless. See this link

far far better than Ekattor and you will get full control over it. Create roles in WordPress and configure their permissions and you can make it a standalone application where the user will not be able to see WordPress ... cosmetically. If the user is a layman, he / she will find it as an application not as WordPress. Yes, you can do whatever you want. And, you know what is the main beauty of this WordPress plugin? You can create multiple schools.
Note: This attached version of Ekattor is not the SAAS version. Version 8 is SAAS which also doesn't work.. I mean it has no module.
