In Chile , some undergraduate majors such as engineering and geology are designed as 6 year programs.     However, in practice it is not uncommon for students to complete such programs over the course of 10 years, while studying full-time without leaves of absence.  This is in part due to a strict grading system where the highest grade of a typical class can be as low as 60% (C-) and the high frequency of protests and strikes organized by student federations and teacher unions, such as the 2011–13 Chilean student protests .
The topic of the thesis is typically based on an existing real-life problem, that is, an issue within the academic fields of the bachelor’s programme. It may be problems in a given organisation (private or public company, interest group, etc.), an industry or the community. You choose/define the topic for your bachelor's thesis yourself, as long as it stays within the academic frames of your programme. When choosing the topic, you might be inspired by a problem, an observation or a phenomenon that you find interesting or by models and theories from courses you have had. It might be helpful to discuss ideas for topic(s) with a possible supervisor for your thesis.
