Midterm 2 guide
COMPSCI 1MD3 · Fall 2026
Every recursion question from the last four years, worked through.
Course notes, from the people who sat the course.
cram is a notes marketplace for one campus at a time. Sign in with your university email, post what you wrote against a real course code, and price it yourself. If nobody has posted what you need, ask for it.
McMaster first. iPhone and Android.
How it works
Three decisions to post. One tap to read.
-
Post what you wrote
Attach the file, name the course and the instructor, set a price or leave it free. Length and format are read from the document itself, so a listing cannot claim to be longer than it is.
-
Read a sample first
Paid listings render about a tenth of their pages as a free sample. You see the depth, the handwriting and the format before any money moves.
-
Ask when it does not exist
Nothing posted for your course? Say what you need and by when. The ask lands in the feed of everyone taking the same class.
Why it is closed
A campus marketplace only works if it is actually the campus.
-
University email required
Signing in needs a working address at a supported university. The check runs in the database rather than in the app, so it holds even for somebody who never opened the app to sign up.
-
Real course codes
Listings attach to the course catalogue instead of a free text subject line. Search for COMPSCI 1MD3 and you get COMPSCI 1MD3.
-
Files stay private
What you buy is stored privately and opens inside the app. It is never a public link that somebody can forward.
If you are selling
Notes you already wrote, for the people taking the class after you.
-
You keep 85 percent
Fifteen percent runs the marketplace. The rest transfers to you through Stripe, which also handles the identity checks and the payouts.
-
Free posts count too
Post at no charge to build a following, or price from $2.00 up. The same listing can answer somebody's ask.
-
Your own work only
Lecture slides, past exams and anything else an instructor holds the copyright in do not belong here, and the Terms say so plainly.
