How are the GMAT essays different from the essays I wrote in school?
Unlike many essays you write in school, you’ll only have 30 minutes, and you won’t be able to use reference materials. Graders won’t be expecting perfection; they will be judging your GMAT essay for what it is: a first draft. Furthermore, the person grading your GMAT essay will only spend 2-3 minutes evaluating your writing.
