Jason, The problem is (IMHO) that you're removing the correct answers from the list so that you "eat away" at your overall list of answers. I would suggest that you maintain two lists in memory: one list is the one with all of the possible answers (basically what you read in button 1 - gSourceData), the other contains the list that gets correct answers removed when they are used so they won't be used again (I'll call it 'gAvailableData'). When you start on a specific drill, you pick a line randomly from gAvailableData for the correct answer and remove it from gAvailableData. You then temporarily copy gSourceData into a temporary variable, remove the correct answer ALSO, leaving you with a temporary variable that only contains incorrect answers. Randomly pick the other three from this temporary variable, and run the drill. For each drill you do, gAvailableData will diminish, but gSourceData will not - thus avoiding the problem of having not enough data to do a drill.
