Subscription service offering crowdsourced study documents, homework Q&A, and expert tutoring for students.
Study Resources is Course Hero's core learning service, giving students access to millions of course-specific study documents, questions and answers, and flashcards contributed by a community of students and educators. Materials are tagged to specific courses and schools so learners can find help for their exact classes.
The service pairs the document library with on-demand expert tutoring available online around the clock, sold as Netflix-like subscriptions to students. Teachers and publishers can also share course content on the platform, extending its catalog across subjects and institutions.
