Cases and such

[theminion.livejournal.com]

My Professor requires that, as practise, we put Интересныи студент into all cases (Nom, Gen, Acc, INST, Prep), and include singluar and plural for each case.
Problem is, I forget the rules for doing so, and we've never actually done plural for the cases.
Can anyone help me?
