❔ Time Table Game Help

Hey-ho, I'm fairly new to C# and programming generally so bear with me. So I'm trying to make a time table game using forms where the player tries to answer many question correctly (into one textbox) under a timer. The timer is up, a another form will pop up showing the results in a listview. The thing I'm stuck with, how add the random values from the question generated into an array (if that the right approach to go by) as well as player's answers and correct too. And having that array goes public so I use in another form. I made a quick table to tried to illustrate how would I organised the data. Thanks in advance.
