Consider the following game

Consider the following game. A referee has cards labeled A, B, C, and D, and places them face down in some order. You point to each card in turn, and guess what letter is written on the bottom. You guess each of A, B, C, and D exactly once (otherwise there is no chance of getting them all right!). You play this game once, and then the referee tells you that you guessed exactly n of the letters correctly. Which value of n is not a possible value of n?
