Why you need unlocks
Course Hero has a searchable library of more than 20 million study documents to help with the classes you’re taking in college. These documents—which are contributed by students and educators—can help you get unstuck, learn new concepts, and prepare for tests.
But when you find a document to study, you may notice that part of it is blurred out. Why? Because the document is locked. When you unlock the document, the blur will be removed, and you’ll be able to see it in its entirety. You’ll also have the option to download the document for further study.
While Course Hero unlocks are always available for purchase, you can also earn them for free. Simply create an account, then log in and complete any of these 3 actions:
|Ways to earn free unlocks
|Number of free unlocks earned
|Upload 10 documents
|Make a quiz
|Rate 5 pieces of content
Study resources for the courses you’re actually taking—whenever you need them.Start here
1. Upload 10 documents
Where to start: Once you’re logged in, share your study resources by uploading documents. Not sure what study documents to contribute to Course Hero? Some examples of study documents include your own class notes, test prep materials, essays, or lab reports. (You can only upload documents if you own their copyrights or have explicit permission from the copyright owners. Please see our uploading policies and copyright protection for more info.)
Reward: For 10 uploads, you’ll earn 5 unlocks.
When you’ll receive them: Usually 1–3 hours to receive your unlocks; can take up to 3 days.
Note: Quality matters. Give your document tags and a helpful, descriptive title so other students are more likely to find it, unlock it, and rate it favorably. Each time they do that, you’ll earn even more unlocks!
2. Make a quiz
Where to start: Go to your unlocked documents and follow the “Quiz Yourself” prompts to create a quiz.
Reward: 3 unlocks.
When you’ll receive them: Up to 1 hour after you create your quiz.
Note: This one-time reward is only available the very first time you create a quiz.
3. Rate 5 pieces of content
Where to start: Rate your unlocked documents.
Reward: 1 unlock for 5 ratings.
When you’ll receive it: Up to 1 hour after you submit your ratings.
Your best bet: Plan ahead, return often
Free unlocks are great—but they can take a little time, so they’re not always practical for last-minute needs. Instead, visit Course Hero often and upload original material over the course of the semester. That way, you’ll grow your unlocks and they’ll be ready when you need them. You can always check your progress by logging in and reviewing your rewards.
