In App Purchase with Student Discount

I'm working on an iPhone app that unlocks further content through an in app purchase. However, I'd like the ability to offer a student discount for the upgrade. I tried creating a second in app purchase at the di开发者_如何学运维scounted price, that you could download from the app after entering a "student code". Apple rejected this as it violates 11.1 of the app store review guidelines. I think they are treating this more like we are selling student codes somewhere and this is outside the in app purchasing.

Is there no way to offer a student discount rate?

Apple does not allow the student discount on any of the App Stores. With the current App Store submission guidelines, you will not be able to offer a student discount.
