Koofers.com provides an interactive community that serves the academic needs of college students through information sharing. Students benefit from collaboration with their peers and the experiences of former students. Many helpful services span the entire academic calendar from course selection through final exams, and include collaborative note taking, course and instructor ratings/grade distributions, and an online library for sharing past exams and study materials. Koofers allows students to make the relatively opaque process of class and teacher selection fully transparent, by providing grade distributions and teacher feedback to allow a student to shape their individual class schedule, based on their own needs and style. Once a student has started the semester, Koofers provides help by offering access to a collective repository of study guides, past exams, etc. This is something schools have had for over a century, but these vaults were only available to small groups of students. Now, those tools are available to all students. Koofers also supports ongoing communication between students and teachers through its community tools.
