Student getting solution that involves very educational experience (8,5)
I believe the answer is:
learning curve
'educational experience' is the definition.
(I've seen this before)
'student getting solution that involves very' is the wordplay.
'student' becomes 'L' (as in L-plates for learner drivers).
'getting' becomes 'earning' (earning is a kind of getting).
'solution' becomes 'cure' (cure can mean a solution or treatment).
'that involves' is an insertion indicator.
'very' becomes 'v' (abbreviation).
'cure' going around 'v' is 'curve'.
'l'+'earning'+'curve'='LEARNING CURVE'
(Other definitions for learning curve that I've seen before include "Process of gaining knowledge" , "Process of increasing understanding" , "Graph of educational progression?" , "Rate of progress in acquiring new skills" , "Educational experience" .)
