On-the-job education and graduation time should be filled in according to the on-the-job study and graduation time of your class during your work. Under normal circumstances, many people will take part in on-the-job study to improve their academic qualifications after graduation from school.
The graduation time can be filled in according to the time on the diploma. The graduation time is generally at the end of June and the beginning of July each year. Regarding the graduation time, I suggest you consult the relevant educational administration department of your school.
