Foolish figure gets very good marks at university with help (6)
I believe the answer is:
assist
'with help' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for assist that I've seen before include "Expedite" , "Help to make" , "Understand by instinct" , "Help, lend a hand" , "Give aid" .)
