Aims In this assignment, you will need to develop a website, "Singapore General Knowledge Quiz", that generates quizzes to test users' general knowledge of Singapore's history and geography. The website should generate quizzes on two topics: Singapore History and Singapore Geography. It will offer to the users to answer questions and score points. At the beginning of an attempt, the user should insert the nickname and choose: "Singapore History" or "Singapore Geography". In each attempt, the user starts with 0 points and can have multiple quizzes on the same or different topic. After the user finishes the quiz, the result with the number of correct and incorrect questions, gathered points from the current quiz ([number of correct questions] * 5 [number of incorrect questions] * 3), as well as the user's overall points in the current attempt (from all quizzes) should be displayed. The user should be offered to start a new quiz on the same or another topic. Also, the user should have the option to see the overall scores of all players in the quiz (Leaderboard cumulative points of all attempts per user), or to "Exit" the quiz. The 'Leaderboard' should give an option to the user to order the players by their nicknames or greatest score. When the "Exit" option is chosen, the nickname and overall points of the user should be displayed. The option to start a new attempt (by entering the nickname) should also be given. The questions for the "Singapore History" and "Singapore Geography" topics should contain both multiple-choice questions (each question with at least 4 choices) and short-answer questions (answers are input via the text field). Every topic should have at least 10 questions in the question pool. In each quiz, 5 questions will be randomly chosen and displayed to the user. During the quiz, the user will answer questions one by one, i.e., each page only displays one question. The user can navigate the questions via the 'next' and 'pre' buttons. The text files should be used for storing the data needed for the website (questions, points per user). Requirements 1. Design Requirements The website should have interfaces for: - Entering the nickname and menu with offered options (quiz topics, Leaderboard, Exit); - Displaying Quiz with 5 questions (one question per page); - Navigating questions via 'next' and 'pre' buttons; - Displaying the result from the quiz and overall points in the current attempt; - 'Leaderboard' with the option to display the list of players (user-points) by their nicknames or greatest score; - Displaying the nickname of the user and overall points (of all - previous and current - attempts) when the attempt is completed (for the "Exit" option); - Restarting the quiz. 2. Functionalities - The user should be able to insert the nickname (at the beginning of the attempt); - The user should be able to choose different topics (at the beginning and after every quiz); - The user should be able to navigate between questions during a quiz; - The user can have unlimited quizzes in one attempt, can see the result of the current quiz and his/her overall points in the current attempt after every quiz; - The user can check the overall points at the end of the attempt, can see the 'Leaderboard'; - The user should have an option to "Exit" and start a new attempt from the beginning and the end of a quiz. 3. Other Expectations - The website should have good interfaces and navigation thru the given options
