Past exam questions and course notes, from your classmates.

Choose your country, college and major when you create your free account. Upload one course note or past exam PDF; once it is approved, the whole archive shared in your major opens up.

For 24 hours, your note is open to a vote by the students in your major who have archive access. If more of them accept it when the round ends, your note is published and you get access to the archive; if more reject it, the note is rejected. If nobody votes or the votes are tied, voting continues with a new 24-hour round (round 2, round 3…). If it does not get enough votes within 8 hours for each of those students (8 hours if there is 1, 16 if there are 2, 24 if there are 3), an admin reviews your note too and decides within 24 hours at the latest. If nobody in your major can vote yet, the admin decides. Other students never see who voted which way.

You will see the reason under your note on the My Notes page. You can try again by uploading a new note that follows the rules.

PDF files with course notes, summaries or past exam questions, up to 25 MB each. Your notes should cover all the topics of a midterm or final. Your instructor's lecture slides, content prepared by someone else, books you have no right to share and documents with personal data such as student details are not accepted.

Yes. Signing up, uploading notes and accessing your major's archive are completely free. There are no premium features or paid accounts; everyone is equal, and only those who contribute to the archive can use it.

By default, only students registered at the same college and in the same major as you who have an approved note. Students without an approved note yet, students in other majors and logged-out visitors cannot see your notes. If you turn on mutual sharing in Settings, other majors at your college or the same major at other colleges in your country can see them too, if they turned it on as well. Your username is hidden by default; you can show it in Settings.

Only a username, password, country, college and major. No email address, phone number or real name is required.

Yes. You can permanently delete your account and all your files from Settings.
