For the GRE General Test, you must write an issue and an argument essay. The two essays are quite different.
To achieve a top score, you'll need to demonstrate that you can write clearly and effectively. To that extent you'll need to accomplish the following:
Your score on the essay section of the GRE exam is used by graduate schools to evaluate your writing and analytical skills. Two separate trained readers will read your essays. They will score each essay based on many factors, and the scores will be combined and averaged. Scores are given on a range from zero to six, in half-point increments. The ETS website provides an overview for both the issue and argument writing tasks, as well as a Score Level Descriptions page.
There are no RIGHT "answers" to the essays, so you can be creative, just as long as you follow a few simple rules and demonstrate a coherent writing style. ETS has made available the complete set of possible essay topics that you can expect to see on the GRE.
Contrary to common belief, writing an essay is not something that happens spontaneously. Luckily, you can improve your writing, and there are several "rules" that you should be aware of to help you compose an essay that is concise, poignant, and easy to understand.
Writing a successful essay requires planning, organization, and practice. The purpose for writing an essay in every instance is to convey a specific meaning to your audience. Developing the message and keeping to a common pattern will help your audience follow along as you make your claims. Your writing should, above all, be your own. It should stay true to your own voice and it should clearly reflect what it is about you that is important for the world to know.
