MUIC's focus on the liberal arts offers a wide range of disciplines and an opportunity to explore different interests. Some students have changed their majors after having taken a class that they really enjoyed. MUIC is one of the few Thai programs in which you can change your major after having started your studies. Another option is to select a minor which enables you to either specialize or broaden your expertise and skills.
Your exploration should also include the web resources available. The Career Development Unit will provide you with links to interesting websites. Do you want to travel as part of your future job? Look for an industry or a position in an organization that will allow such a possibility. Looking at starting salaries for different jobs may also be helpful in deciding your future career.
