The Exploratory Studies program at Purdue University allows undergraduate students up to four semesters to explore academic majors and career paths before selecting their specific field of study. Through a highly supported advising process and the required EDPS 10500 (Academic and Career Planning) course, students assess their interests, strengths, and goals, receiving personalized advising and course schedules tailored to their evolving interests. Upon completion of up to four semesters, students transition (CODO) to a degree-granting major of their choice. 来源： https://www.purdue.edu/exploratory/incoming/explore-majors-careers.php
