Could you clarify what you mean by "mark detail explanation"? Are you referring to: Marks/Grades (e.g., how marks are awarded in exams or assignments)? Marking/Annotation (e.g., how to mark up a document or text)? Mark in a specific context (e.g., a brand, a person named Mark, a marking system)? Let me know so I can give you the best explanation! ???? You said: ... https://austratech.com.au/services.html
