Course Hero

Course Hero is an online learning platform offering a massive library of study resources — lecture notes, study guides, practice problems, and step-by-step explanations — shared by students and educators, plus homework help from tutors. With tens of millions of documents covering courses across thousands of institutions, it's a go-to when students want to see how others approached an assignment, study a topic, or get unstuck.

Its model combines a crowdsourced document library (upload your own study materials to earn access, or subscribe) with on-demand tutoring where you can ask questions and get expert explanations. AI features have been added for faster explanations, summaries and study support, modernizing the platform alongside its human-answer model.

Access works two ways: earn free unlocks by uploading your own quality study documents, or subscribe (around $9.95–$19.95/month depending on plan and billing) for direct access to documents and tutor questions.

Strengths: an enormous library where course-specific materials often already exist, the earn-by-uploading option for budget-conscious students, and combined resources plus tutoring. Weaknesses: quality of user-uploaded documents varies, subscription costs add up, and — importantly — using Course Hero for graded assignments or exams is considered academic misconduct at many institutions, which actively monitor it. Use it to study and understand, not to submit others' work.

For students wanting supplementary study materials, worked examples, and homework help, Course Hero is a large resource — best used ethically as a study aid, with the same integrity caution that applies to Chegg.
