Here's why:
* Synthesizing and drawing conclusions means you've brought all your ideas together and formulated a clear, concise argument.
* Revising and editing takes that argument and refines it. It involves:
* Checking for clarity, conciseness, and coherence.
* Ensuring smooth transitions between paragraphs.
* Evaluating the effectiveness of your evidence and analysis.
* Polishing your writing style for grammar, punctuation, and spelling.
Essentially, after you've reached your conclusions, you need to make sure they're presented effectively and that your essay as a whole is polished and ready for an audience.
