AppStore in-app purchases for levels
I'm part of the Apple Developer University Program from our university. We would like to provide a game for children with many different levels. The problem is, that we are going to start with just a few levels and want to increase the amount later. But we want to give the user the ability to choose/download the levels which he can play. Therefore I thought it could be solved by using in-app purchases for levels. So the user can choose a level and download it.

My problem is, that because of my limited developer account I can't get into the "AppStore Review Guidelines" page from Apple. So I do not know if this is allowed or not. Furthermore we would like to deliver the levels for free but I've heard that in-app purchases can't be free? So it's possible to provide a level (=a in-app purchase) for 0.01$? :)

Our first approach was to give the user the possibility to download a level from our server out of the app. But we've heard that this will definitely be rejected by Apple? Is this true?

I'm thankful for any advice.
