In crowd Scots frightened posh student (8)
I believe the answer is:
graduate
'student' is the definition.
(I know that graduate is a type of student)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for graduate that I've seen before include "University alumnus" , "University type" , "Successfully complete a course in higher education" , "Person who has gained university degree" , "Move to the next stage" .)
