3. The academic system of in-service doctoral students can usually be extended to 5-7 years, and that of full-time doctoral students is generally 3-5 years. This is because in-service doctoral students usually can only allocate a certain amount of time for research and study outside work every week, and the progress is relatively slow.

Please note that the requirements of each school and major may be different, so it is best to consult the admissions office or relevant departments of the school you are interested in to find out the specific academic system of in-service doctoral students under their guidance.

For different universities and countries, the academic system policy of in-service doctoral students may be different.

1. Length of study: The length of study of in-service doctoral students is usually longer than that of full-time doctoral students, because in-service doctoral students need to arrange their work and study reasonably and have more flexible time arrangements. The duration of schooling is generally between 3 years and 7 years, depending on the regulations of each university.

2. Learning style: On-the-job doctoral students usually study courses by flexible learning or distance education, which is convenient for them to take care of both work and study. This learning style can be flexibly arranged according to the individual's time and place.

3. Curriculum arrangement: The curriculum arrangement of in-service doctoral students is generally combined with professional courses, research topics and thesis writing. According to the individual situation and research direction, the school can provide different curriculum combinations.
