The NCCU Course Rate Tool is a free Chrome extension designed to enhance the course selection experience for students at National Chengchi University (NCCU). It allows users to view comprehensive evaluations of courses directly on the university's course inquiry platform, eliminating the need to manually track and check ratings for each course individually. This tool also includes a historical selection ranking feature for general education courses, providing insightful data for students.

Additionally, the extension introduces a class schedule preview function, simplifying the process of organizing courses without the hassle of using spreadsheets. The tool aggregates evaluations from the academic year 1011 to the present, focusing on courses with the same title and instructor. However, it should be noted that courses with different names may not yield results, and users are encouraged to report any missing evaluations through a designated form.
