26 young people from all over the world are studying at the European School of Management and Technology,the ESMT,to earn their MBA degree within a year. That means hard work -- including on weekends. In part three of our series,Managers of Tomorrow,we accompany Laura and two of her fellow students on a visit to Berlin's Carnival of Cultures during some of their rare leisure time. For Laura from Argentina,the annual event represents what she likes best about Berlin: the big city atmosphere with people from all around the world. After a day off,it's back to work. At the ESMT students are also assigned to a psychologist,who analyzes their individual strengths and weaknesses. Laura,for example,needs to learn how to assert her interests better. The students also take a field trip -- to India. Their goal is to figure out the secret of success of the sub-continent's rising economy. Report by Wolf Gebhardt & Michael Wetzel.
