 The School of Oriental and African Studies has become the lead college for the external degrees previously led by Imperial, while Imperial offers its own Global MBA, the University of London now offers Global MBA led by Queen Mary University of London, which is accredited by Chartered Management Institute and Chartered Institute of Management Accountants.In Europe, North America, the Middle East, South Asia and East Asia many students participating in University of London International Programmes seek out tuition at one of the more than 150 private or non-profit institutions that prepare students for University of London examinations.Such institutions may be audited and, if found to meet quality standards, may become "recognised" by the University for the support offered.
