Interesting answers above. Never thought about this before and find my answers very strange though i doubt they will be to anyone else.

School : Pure maths, music, spanish, and electronics. Hated PE but loved to training for and playing competitive sport outside of school as a junior, probably because i loved the sport itself.
6th form: Electronics, but not maths, physics or chemistry.
Uni: I don’t remember liking any of my EE degree (which i didn’t get to finish for different reasons :D)

I’m naturally disposed to learning and have always self-studied in some form or other so am surprised how i liked so little during formal education.
