Most churches, coaching centres, and faculties in this market already live on WordPress. You should not rebuild that. Install a plugin, keep your theme, let TribePeer run the classroom.
The plugin wraps the website classroom and talks to TribePeer from PHP. You do not get a second backend, a second student list, or a second set of grades.
Request it here, pay securely, and we email the package. That is deliberate: a public directory listing comes later. Until then you get a copy that matches your organisation, not a random zip from a search result.
