全球健康的挑战

• 我什么时候能够访问课程视频和作业？

  Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:

  • The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
  • The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

• 我购买证书后会得到什么？

  您购买证书后，将有权访问所有课程材料，包括评分作业。完成课程后，您的电子课程证书将添加到您的成就页中，您可以通过该页打印您的课程证书或将其添加到您的领英档案中。如果您只想阅读和查看课程内容，可以免费旁听课程。

• 退款政策是如何规定的？

  您可在付款后两周内，或者在课程第一个班次开课后（对于已启动的课程）两周内，获得全额退款，以其中较晚者为准。获得课程证书后，您便无法再退款；即使您在两周的退款期内完成了课程，也是如此。请阅读我们完整的退款政策。

• 有助学金吗？

  是的，Coursera 可以向无法承担学费的学生提供助学金。点击左侧‘注册’按钮下的‘助学金’链接即可申请助学金。您可以根据屏幕提示完成申请，申请获批后会收到通知。了解详情。

• Will I receive a transcript from Duke University for completing this course?

  No. Completion of a Coursera course does not earn you academic credit from Duke; therefore, Duke is not able to provide you with a university transcript. However, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

• 完成课程后，我会获得大学学分吗？

  此课程不提供大学学分，但部分大学可能会选择接受课程证书作为学分。查看您的合作院校，了解详情。Coursera 上的在线学位和 Mastertrack™ 证书提供获得大学学分的机会。
