putnam competition

The William Lowell Putnam Competition is an annual mathematics competition for regularly enrolled undergraduates in colleges or universities of the United States and Canada, who have not yet received a college degree. Prizes are awarded to individual participants and institutions.

The Putnam examination tests originality, technical competence and familiarity with the formal theories embodied in undergraduate mathematics. Questions cut across the bounds of various disciplines, and include self-contained questions that do not fit into any of the usual categories. These self-contained questions can involve elementary concepts from group theory, set theory, graph theory, lattice theory, number theory or cardinal arithmetic.

The Putnam mathematical competition takes place on the first Saturday in December. The examination consists of a morning session 8-11AM (08:00-11:00) and an afternoon session 1-4PM (13:00-16:00) with a 2 hour break in between.  For Putnam 2021, the exam will take place on Saturday, December 4, 2021 (2021-12-04) from 8-4PM (08:00-16:00) on campus (MS, 6627).

The UCLA Mathematics Department coordinates the UCLA Putnam team and runs activities such as

  • A “Problem solving” course (Math 100) is offered each fall. This is an excellent preparation for the Putnam competition. In Fall 2021 the course is taught by Professor Sarkar and meets MWF 12:00-12:50PM.
  • An introductory preparation session, open to all students (whether or not enrolled in Math 100), will take place on Friday, September 24, 2021 (2021-09-24) from 4-5:20PM PST (16:00-17:20) on campus in Franz, 1260.
  • We will have a practice exam on Monday, September 27, 2021 (2021-09-27) from 4-6:50PM PST (16:00-18:50) on campus in PAB, 1434A.
  • The top scorers on the practice test are invited to be part of the extended UCLA Putnam team, which receives intensive weekly preparation in the Advanced Problem Solving Seminar (Math 101, Mondays 4:00-6:50pm).  
  • Year round consulting for students who want to learn more about the Putnam competition, for example study old exam questions. Professor Sucharit Sarkar, sucharit@math.ucla.edu, is available to help.
  • Free pizza for lunch on the day of the competition.

Participation: All enrolled UCLA undergraduate students which do not have a college degree may participate in the Putnam exam. There is a four time limit for any participant. The top three scorers from UCLA form the UCLA team, and their total score is the UCLA team score. In addition, they and all the other participants compete for individual scores.

Prizes: The top performing UCLA student will receive the Basil Gordon Prize, valued at $1,000.  All the UCLA students placing in the top 100 nationwide will receive a Putnam Performance Prize where the amount will depend on the nationwide rank.

Reasons to participate: Students taking part in and preparing for the competition learn a lot about general mathematical skills such as solving problems and proving statements. Graduate schools and other employers can be impressed by high Putnam scores.

Preparation: Check here for more resources and information about how to prepare for the exam.

Time and Location: The Putnam mathematical competition takes place on the first Saturday in December. For Putnam 2021, the exam will take place on Saturday, December 4, 2021 (2021-12-04) from 8-4PM PST (08:00-16:00) on campus at MS, 6627.  There are two sessions, a morning session from 8 am to 11 am and an afternoon session from 1 pm to 4 pm. There are 6 problems in the morning session and 6 problems in the afternoon session. Each contestant works independently with no collaboration. Results of the competition become known around March of the following year.

Registration: Participants have to register directly with the Putnam organizing committee prior to the exam no later than Friday, November 26, 2021.  To register, go to https://artofproblemsolving.com/contests/putnam/student.

Contact: For general inquiries contact Professor Sarkar at sucharit[at]math.ucla.edu.

Past results:  Putnam 2020 was conducted in unofficial mode due to COVID with no official scores, winners, or awards. In the 2019 Putnam Mathematical Competition, the UCLA team (Ciprian Bonciocat, Jacob Zhang, Kaiqi Zhu) was ranked #4 out of 570 institutions. 

A total of 4,229 students from 570 colleges and universities in the U.S. and Canada participated in the competition.  Among them were 36 UCLA students. Five of them were in the top 100 overall and received Prizes or Honorable Mentions:  Jacob Zhang (rank #23, score 82), Kaiqi Zhu (rank #34.5, score 72), Ciprian Bonciocat (rank #56.5, score 61), Runze Yu (rank #90.5, score 51), and Baiqing Zhu (rank #101, score 50). Fourteen other UCLA students were ranked in the top 500 nationwide (in alphabetical order):  Bryan Hu, Arihant Jain, Chenfei Li, Isaac Li, Justin Li, Yuhan Liu, Tang Mohan, Alexandru Pascadi, Tachin Ruangkriengsin, Glenn Sun, Yan Tao, Ken Willyard, Alexander Wong, and Hongyu Zhu.

The Basil Gordon Prize, for the top scorer among UCLA students, will be awarded to Jacob Zhang. The Putnam Performance Prizes for UCLA student(s) who placed g in the top 100 nationwide will be awarded to: Jacob Zhang, Kaiqi Zhu, Ciprian Bonciocat, Runze Yu, and Baiqing Zhu.
