Additional study, source of help that inspires young college student (9,6)
I believe the answer is:
refresher course
'additional study' is the definition.
'refresher course' can be an answer for 'study' (thesaurus). I'm unsure of the 'additional' bit.
'source of help that inspires young college student' is the wordplay.
I cannot really see how this works, but
an anagram of 'source' is 'course' which is located in the answer.
'student' could be 'fresher' (fresher is a kind of student) and 'fresher' is found within the answer.
The remaining letters 're' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for refresher course that I've seen before include "it helps you get up to speed" , "further education?" , "study update" , "Training" , "sweet group?" .)
