Study Abroad - Activity or Education for Common App

Hello All - My daughter studied abroad for a year in Japan. She has it listed in her activity section on her application. I think it should go in the education section as she was there for an entire school year AND she received pass/fail credit for most of her classes.

Which one of us is correct or does it matter?

Which apply to her HS graduation credits? Then, education.

Thanks @skieurope
