Olympiad Training for Individual Study (OTIS)

OTIS is an olympiad training program for students aiming to do well on USA(J)MO or similar level contests. It is designed for contestants who are comfortable reading and writing proofs and can usually qualify for national olympiad (for example, consistently 10+ on AIME for American contestants is fine). Students at other levels may be interested in my list of mentors and programs.

The OTIS Excerpts#

Around the start of 2019, I posted publicly a collection of 192 problems and solutions based on materials for OTIS. This mini-book was named The OTIS Excerpts. It is designed to mostly be beginner-friendly though some of the chapters are more challenging.

Application — Year VIII#

The regular deadline for 2022-2023 is August 1, 2022 at 11:59 PM Pacific time. See the instructions for details about late application.

Who can apply#

OTIS is open to anyone, including international students from all countries.

Students from minorities and underrepresented groups are especially encouraged to apply. (I promise I don’t bite.) Admissions is done primarily based on perceived preparedness; it is not a merit-based competition. Also, financial aid is possible.

OTIS is taught in English and assumes an ability to read and write proofs. A stable Internet connection is required.
