All students have to write essays. Essays are short pieces of writing that provide a writer’s perspective on a certain issue or tell a story. There are many types of essays. They can be formal, informal, persuasive, descriptive, or informative. Some essays help writers share their personal experiences, while others address serious topics, such as global warming or inequality. Writing an essay is always a challenging task because you not only need to study a topic and come up with an interesting opinion, but also have to create the right structure and format.
