每门课程都进一步分为多个单元，每个单元都有学习资料（PDF文档），并且提供了自我评价的方法。

Each course is further divided in modules, each module coming with study material (a PDF document), and offers the option for self-assessment.

库的评价标准有库的功能性资源、文档、库的教程质量、库的扩展难度等。

Libraries can be evaluated in terms of their functional resources, documentation, the quality of their tutorials, how easily they can be extended, and so on.
