I am aware that I cannot disclose key information about the system/business model but I would only need to know if there is record of previous education systems being patented. It isn't just a software but an entire educational process, explained in detail.
There are certainly many patents that cover educational systems. A few that came up in a quick search:
Online educational system with multiple navigational modes US8727781B2
Vertically integrated mobile educational system US9324240B2
Real time learning and self improvement educational system and method US8602793B1
On-line educational system having an electronic notebook feature US6965752B2
You need to do a better search if you are interested in moving forward.
