本模块介绍OFFICE的操作技能。学习的主要目标是熟练应用WORD、PowerPoint和Excel这三大工具软件。如果你对这些内容已经很熟悉，可以忽略它。对多数学习者来讲，通常能够用WORD进行基本文字编辑，或还能用PowerPoint制作简单的幻灯片。但这些工具软件通常会具有比你所了解的更强大的功能；同时，Excel电子表格软件更是财经、管理等专业的必修基础。因此，还是认真的学习一下，掌握这些工具软件更多的功能。

Frequently asked questions
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.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
