Putnam
Session A and Session B
The hardest undergraduate competition, in the real A/B format: a six-problem morning sitting, then a six-problem afternoon sitting, each climbing from A1/B1 to a very hard A6/B6. Four original papers with complete worked solutions.
How a paper runs
12 problems · 6 hours
- Two sessions, A and B, of 6 problems each. Each session lasts 3 hours.
- Each problem is worth 10 points. Full credit needs a complete proof.
- Here every problem also has a numeric target, so your answer can be checked.
- Session A is handed in before Session B is opened.
