It's as far as we've got in higher education (4)
I believe the answer is:
here
'it's as far as we've' is the definition.
I can't judge whether this defines the answer.
'in higher education' is the wordplay.
'in' says the answer is hidden in the clue.
'HERE' is hidden in the letters of 'higher education'.
'got' acts as a link.
Can you help me to learn more?
(Other definitions for here that I've seen before include "Present; I say!" , "To hand" , "Present - at this point" , "On this spot" , "At this stage" .)
