Develop me a quiz mobile app as i use later for my student

Develop a quiz app using Android Studio. This app is available only for Android OS only. Only develop one app but must have two different type of user (teacher) and (student). Meaning when user register, can choose role as teacher or student. The app allow users to login and create a new account using email, and the data will be saved on Firebase. The quiz questions is multiple choice quiz type. Only text use in the questions no need images or videos needed.

For teacher side, teacher are able to upload new quiz (enter quiz and answers) and able to view student’s results. Include also the time taken for student to answer the quiz. Each set of quiz only available for 10 quiz questions. 1 dummy set prepared is enough the rest let me add by my own since this app will be use by me.

For the admin part which is in Firebase later, me myself will be an admin.

For student’s side, student can choose the quiz they wish to attempt, answer the quiz questions and see their result at the end of the quiz attempting (showing how many wrong and correct questions they get). Every time student answer the quiz question correct and wrong question will play sound that related to both correct and wrong answer options.

Serious note: Please bid fix price. Example if you bid 50$ meaning the payment i need to make is 50$.
