You need an undergraduate degree in a relevant discipline, with a final grade in the top 10% of your graduating class. Most incoming students also hold a Masters degree.
You must submit a Graduate Management Admission Test (GMAT) or Graduate Record Examinations (GRE) score that is no more than five years old. You are unlikely to gain admission with a GMAT score below 690. GRE quantitative and analytical scores should be above the 90th percentile.
You need to give details of two referees. They should be faculty members who know your work well and can judge your research potential - for example, previous supervisors or academic tutors.
Essays form an important part of your application. Make sure you spend a significant amount of time on them. You can also attach a CV up to two pages long.
