You must take the GMAT or GRE by the application deadline. See Application Process for GMAT/GRE test date ranges. Unofficial scores are acceptable at the time of application, but every applicant must request to have their official score submitted to HBS. You do not need to have the results of the AWA section of the GMAT or GRE in order to apply; however, we do expect you to complete this portion of the exam and we will require an AWA score for anyone admitted to the program.
