Free Study Resources and Reading Plans: 150 Books and Courses That Cost Nothing

<p>A course is a better thing than a textbook in one specific way: it tells you the order.</p> <h3>The courseware comparison</h3> <table><thead><tr> <th>Platform</th><th>Courses</th><th>Includes</th><th>Video</th><th>Assessment</th><th>Best use</th> </tr></thead><tbody> <tr><td>MIT OpenCourseWare</td><td>~2,000+</td><td>Lecture notes, assignments, exams, readings</td><td>Yes, many courses</td><td>Exams with solutions, no grading</td><td>Following a full syllabus unaided</td></tr> <tr><td>OpenLearn (Open University)</td><td>~300+</td><td>Notes, activities, self-assessment quizzes, some video</td><td>Some</td><td>Quizzes with feedback</td><td>Guided self-study with structure</td></tr> <tr><td>Saylor Academy</td><td>~300+</td><td>Full course pages, readings, discussion prompts</td><td>No</td><td>Assignments, no credit</td><td>Accounting and business pathways</td></tr> <tr><td>Khan Academy</td><td>Thousands of short lessons</td><td>Video, practice problems, mastery system</td><td>Yes, throughout</td><td>Auto-graded exercises</td><td>Drilling the basics, gap-filling</td></tr> <tr><td>LibreTexts</td><td>Thousands of pages</td><td>Peer-reviewed wiki textbooks, homework</td><td>No</td><td>Problem banks</td><td>One textbook spread across many books</td></tr> <tr><td>NPTEL (India, NPTEL)</td><td>Thousands</td><td>Lecture videos + transcripts + books</td><td>Yes</td><td>Assignments via SWAYAM</td><td>Engineering and science at lecture level</td></tr> <tr><td>Academic Freedom Project</td><td>Hundreds</td><td>Lecture videos with transcripts</td><td>Yes</td><td>No</td><td>Primary-source-driven US history and civics</td></tr> <tr><td>Pressbooks</td><td>Thousands of books</td><td>Self-published textbooks with web/PDF/ebook export</td><td>No</td><td>No</td><td>Courses with a strong reading list</td></tr> </tbody></table> <p>MIT OCW and OpenLearn are complete <strong>course packages</strong>. Khan Academy and NPTEL are <strong>lecture collections</strong> — superb for drilling a specific topic, less good as a spine because they were never sequenced into a course. LibreTexts is a <strong>textbook platform</strong>, not a course, but its homework banks are extensive.</p> <blockquote><p>A textbook tells you what to read. A course tells you what to read, in what order, and what problem to attempt afterwards.</p></blockquote> <h3>Saylor Academy</h3> <p>Saylor runs roughly three hundred free, self-paced courses, with unusual depth in accounting, business and the social sciences — free courses on financial accounting and corporate finance exist in full. No fee, no enrolment limit, no credit. Expect 15 to 25 hours per course.</p> <h3>Khan Academy</h3> <p>The right tool for a specific job: <strong>closing a gap you can name</strong>. "I do not understand partial fractions", "I do not know how to normalise a distribution" — Khan is close to unbeatable. The mastery system does not move on until you are right, and it tells you whether you are guessing or learning. Its weakness is depth: superb for the first two years of a subject, thin on third-year material, laboratory work and anything requiring an opinion.</p> <h3>NPTEL</h3> <p>The Indian government's National Programme on Technology Enhanced Learning provides lecture courses with video, transcripts and downloadable books, mostly in engineering, science and management, taught by professors from Indian institutes of technology. Many courses are free to watch; some certificates are paid. The transcripts make the videos searchable, which matters more than it sounds — you can find the ten minutes of a two-hour lecture that covers your problem.</p> <h3>LibreTexts</h3> <p>A wiki-based textbook platform with peer-reviewed pages. Its distinctive strength is <strong>homework</strong>: thousands of question banks with worked solutions, and a "Studio" feature that turns a page into a self-marking exercise. Many popular books exist here in parallel with a conventional PDF. Check the page history before you rely on a page — wikis get revised.</p> <h3>Academic Freedom Project</h3> <p>A US history and civics library of lecture videos with full transcripts, covering the American Revolution through the twentieth century, each anchored in primary documents. Transcripts mean you can read instead of watch, which is faster and searchable.</p> <h3>How to use a free course when you are not enrolled</h3> <ul> <li><strong>Get the syllabus, not the videos.</strong> Most courses publish a syllabus with the week-by-week plan. That plan <em>is</em> the course. Put it in your calendar before you watch anything.</li> <li><strong>Watch at 1.5× or read the transcript.</strong> If transcripts exist, read. If not, the second viewing is where the learning happens; the first is for orientation.</li> <li><strong>Do the assignments on paper, closed-book.</strong> The moment you look at a solution, the problem is gone. Write your answer first, then compare.</li> <li><strong>Do the exam last.</strong> OCW exams are usually published with solutions. Take the exam under time pressure before you open the solution file, and mark your own work honestly.</li> <li><strong>Write a one-page summary per week.</strong> Half a page of your own words on what you did not understand is worth more than the videos.</li> <li><strong>Pick one anchor course and finish it.</strong> Finishing a single course end to end teaches more than sampling eight.</li> </ul>
