Seconds needed after most of dessert course (8)
I believe the answer is:
syllabus
'course' is the definition.
(academic course)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for syllabus that I've seen before include "Course list of subjects" , "List of subjects for study" , "(School) subjects" , "Outline of subjects included in course of study" , "Prescribed course of study" .)
