It might be harder for younger ears ;~)
Would '39' qualify as "younger ears"? My wife got 10/10 and identified every piece as well...listening from the other room through my laptop speakers. She thought it ridiculously easy and asked if there was another level to try out. My 46 year old ears, with far less classical exposure got a D perhaps...6/10. I'll be taking the makeup exam after I attend summer school. What a looser!
