Sloan advises you to do a few things for your reapplication. Reapplicants are advised to obtain a new letter of recommendation; it can be from the same person, but it should be updated to reflect how you’ve changed since your previous application. Make sure your application is not the exact same as the first one.
Sloan recommends using different examples to highlight your strengths and skills. You are not required to answer the optional question, but you can if you believe it will help strengthen your reapplication. MIT Sloan will review your reapplication alongside your previous application, so it is important to keep that in mind when completing your new application.
