I have an upcoming event where we’re selling tickets to students from the Faculty of Engineering. I need a spreadsheet to manage student names, and I want to filter them by department into separate sheets, so I can track ticket sales for each academic year. Each academic year is divided into two categories: Old Regulations and New Regulations. The departments are: Preparatory Computer Engineering Communications Engineering Electrical Power Engineering Mechanical Power Engineering Mechanical Production Engineering Architecture Architectural Planning Civil Engineering Petrochemicals Artificial Intelligence (AI) Mechatronics Environmental Architecture Renewable Energy Construction Engineering I also need a counter to calculate the number of tickets sold per academic year/category.
