The outline you provided is an example of topic form. In topic form outlines, the main ideas or sections are presented as short phrases or single words rather than complete sentences. Each item represents a key concept related to the main topic.
In your example:
I. Passing the exit exam for high school
A. Requires study
B. High school credits
C. Graduation requirement
D. Senior year
Each point conveys a specific aspect of the topic without elaborating into full sentences.
If it were in sentence form, each point would be constructed as a complete sentence. In paragraph form, the ideas would be presented in a continuous text format instead of an outline.
