Earth Learn
Having read is not having measured
A lesson, a mark and a practice answer are learning. They are not an environmental result.
When you mark a lesson as read, one learning count is saved. It is 1, and it cannot be exchanged.
A practice answer shows whether you read the statement in the lesson. It does not raise the evidence level.
Audio, video and files to download are not published. The text is the whole lesson.
Source: Accounting rule for Earth Learn. Not a study of learning.
Accessibility: Text without audio or video. The paragraphs are short. There is no time limit.
Where it applies: Applies in any climate. No local study is attached to the text.
Practice
An answer shows whether you read the statement. It does not raise the evidence level and it earns no recognition.
What does a practice answer do?
