I did not get this 5% last year though I paid my fee using discover card (it had 5% too for tuition part at that time). However, in the statement this transaction was classified under 'government' category instead of education/tuition. I called discover and was told that the reason may be our university is a State university. You may try a small transaction first and see if it qualifies. Otherwise, using some other 2% cashback card will be better than nothing.
