hello timothy, nice video. I am working in creating a multiple choice type exam in excel, where i want to keep one of the sheet as the database which contains questions and the choices, say 200 questions and choices. when i open the excel file, i must get a sheet where it should display 20 questions that is randomly selected from the database. could you please explain how to do this?
