Some points to keep in mind before writing an Exemplification Essay:
An exemplification essay starts with a broad statement about the subject.
Once a generalization has been identified, build on it with instances that are applicable to the purpose of the given opinion and strengthen the integrity of the paper.
Make a sensible arrangement of the samples.
Keep in mind that this is a well-supported generalization. Don’t make generalizations in a hurry. The audience must be able to understand the rationale used in the work.
