Quiz game coding structure?

Hi everyone! I am suppose to develop a quiz kinda game and I have been wondering how can I do it. Here’s how the game should go. Player can navigate thru 5 places. In each place, there will be 20 questions which will pop out when the player clicks on the buttons respectively. 20 questions, 20 buttons in each place. There will be a timer and a score board which will take note of the score. Which I dont know how to do! If player correct in first attempt, 10 marks, sec attempt, 5 marks, and so on. Now the question is I am not sure how am I going to develop the game in terms of coding structure. So can someone please suggest or recommend how can I do this? Thanks a dozen to viewers and helpers! :slight_smile:
