No, your MBA essay is at least as equally important as your GPA and GMAT score. While your GPA and GMAT score are good indicators of your academic abilities, the MBA essay is the first opportunity you will have to allow the admission committee to get to know you more personally.

Most business schools use a holistic approach to assessing applications, and your response to the essay question can determine whether you are a good fit for the program.
