Advanced INDEX MATCH (I think)

Hi,

I have a list of tutors who have picked various titles to tutor. I'm then wanting a master list to figure out who picked what. Many tutors picked more than one title. This makes more sense visually, so I've included a sample spreadsheet. I feel like it's some sort of advanced Index Match, but haven't got it to work.

Thanks in advance.

Best wishes


Hayden
