Partly the reason where undergrads aim? (2,1,6)
I believe the answer is:
to a degree
'partly' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for to a degree that I've seen before include "Up to a point" , "Somewhat" , "Where undergraduate is heading" , "Rather!" , "in part" .)
