First class date passed without trouble (4)
I believe the answer is:
aced
'passed without trouble' is the definition.
I can't tell whether this defines the answer.
'first class date' is the wordplay.
'first class' becomes 'ace' ().
'date' becomes 'd' (common abbreviation eg in DOB, date of birth).
'ace'+'d'='ACED'
Can you help me to learn more?
(Other definitions for aced that I've seen before include "passed with highest marks in US" , "Comprehensively beaten" , "Reached a golf hole in one shot" , "Sailed through" , "got a hole in one" .)
