New Topic/Question

i'm a beginner in programming and I'm currently working on a multiple choice quiz.
Both options branch out into 3 separate quizzes.
(Example, User chooses "Riddles" --> option 1: Animals , option 2: Logic , option 3: Objects)
At the end of these quizzes, the user is given the options to return to main menu (to choose a different Subject) or the option to return to the Subject menu to pick another quiz and the final option is to quit altogether.
I am aware that I am not using arrays and only methods, everything runs fine, but I would like to add another feature to the program.
How do I code the program in a way where the user can exit the program without having to complete all of the questions in the current quiz they're in?
