最近在填eRAS申请，请问各位前辈 clinical externship/observationship 填的是
work experience 还是volunteer experience?
eRAS网站上的介绍如下，
Clinical and Teaching experience should be treated as Work experiences.
Include all unpaid extra-curricular activities and committees you have
served on as Volunteer experiences. After completing the required fields,
click Save. Additional entries may be added as needed.
这段话比较confusing，第二句不知道是独立的还是对第一句的补充。
