Looking for free study guides to help with school or exam preparation? The good news is that there are plenty of legal resources available online—you just need to know where to look. These guides can help you review subjects, understand key concepts, and prepare more effectively, all without spending a dime.
1. Start with Trusted Educational Websites
Websites like Khan Academy, OpenStax, and CK-12 offer free study materials across a wide range of subjects and grade levels. These platforms are well-known for their high-quality, peer-reviewed content and are completely legal to use.
2. Use Government and University Resources
Many schools and government education departments offer free study materials. Check out websites like USA.gov, your state’s department of education, or university open courseware platforms (like MIT OpenCourseWare). These often include downloadable guides, worksheets, and practice tests.
3. Visit Online Libraries and Repositories
Platforms like Project Gutenberg, Internet Archive, and OER Commons provide access to thousands of free educational resources. While not all are traditional study guides, many include textbooks, summaries, and supplementary materials.
4. Search by Subject or Exam
If you’re preparing for a specific test (e.g., SAT, GED, or AP exams), try searching for “free SAT study guide PDF” or similar terms. Make sure the site is reputable—look for .edu, .org, or government domains.

5. Join Student Communities
Online forums like Reddit’s r/Study, or student-focused Facebook groups, often share links to legal, free study resources. Always verify the source to avoid pirated materials.
By using these legitimate sources, you can access helpful study guides without risking legal trouble or low-quality materials. Happy studying!
