First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main idea of taking lecture notes. It is a general statement that does not need other sentences for context. It does not start with a conjunction or use pronouns. Why other lines are not chosen? Paragraph 2 starts with 'To be' which makes it dependent on the first idea. Paragraph 3 starts with 'Get' which is not a general statement. Paragraph 4 starts with 'Once' which shows it is dependent on previous ideas.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the ideas. It shows the result of the actions taken in the previous paragraphs. It gives a clear conclusion about the importance of reviewing and revising.
