Hi, I'm looking for a way to analyse student performance in past papers (specifically Cie IGCSE Science) to identify their key areas of weakness in terms of both subject knowledge and skills. I'm thinking it will take the form of some sort of excel spreadsheet. Into which I can input their marks for individual questions and it will refer to a database of past papers topics and skills but does anyone know of anything that already exists to do this? It's a large undertaking but I think it would be a useful resource moving forward so worth the time investment. Thanks if you have any ideas!
