OK, so you seem to be having a data modeling issue. First, abandon the concept of arrays; Core Data doesn't use them, and you're really talking about set theory, so we'll talk about sets. So you want to have a set A of subjects. You also want a mapping F from a subject to a set of what sound to me like flashcards. Elements of set A are of type Subject, elements of set F(A) are of type Flashcard. A Subject has a title, and a Flashcard has a front side and a back side. >From here, it should be very clear how you would model this in the Core Data model designer.
