In 1978, Rousseff attended the Campinas State University, with the intention of receiving a master's degree in economics. At that time, she began attending a discussion group formed by other VAR Palmares former members, such as Rui Falcão, Antonio Roberto Espinosa, and eventually Carlos Araújo. Meeting once every three months, the group lasted a couple of years. They would read the works of Karl Marx, Nicos Poulantzas, and Louis Althusser, discussing what would be the right moment to resume their political activity. Rousseff declared that she "attended the master's degree program", but did not finish it, failing to present her thesis. "That's why I returned to university to pursue a doctorate. And then I became minister and did not finish the doctorate", she said. Her academic credentials have been the subject of controversy as her official biography listed these master's and doctoral degrees that she had never earned. She was, however, twice enrolled in the graduate program in economics at the State University of Campinas, without ever fulfilling the requirements for those degrees.
