[Question]How-To make a Trivia/Quiz App?[Please View]

Hi everyone! I am a 14 year old student(9th Grade), and I want to make a (Large-Scale) Trivia/Quiz app. It is going to have several categories and people have to choose the right answer out of 4 given. I am new to this and I need help on how to make it. Especially the part with reading the questions and answers from an external file, then detecting if the player chose the correct answer etc. So if anyone is willing to teach me, I am willing to listen and learn. Please anyone? I already have skills in programming I just need help with the data, and foundations of the app, etc. I can do all the art and illustrations for the game I just need help with starting it. I can add my own questions and categories later.

Please Respond A.S.A.P, I need to learn soon to start my project.

Thanks- Steven
