It’s supra-curricular NOT super curricular!

Sorry just had to say it as it bugs me, especially on WIWIKAU as it’s rife there.
Supra - over and above.

As opposed to super, meaning "over and above"?

Both Oxford and Cambridge university websites disagree with you, for what it's worth.

I don't think so

Oxford says : What is 'super-curricular'?
'Super-curricular’ activities are educational activities which go above and beyond the school curriculum.

Ouch! This isn't going to go down well..
