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 was August 1. Late applications are now open, and will remain open until April 15.

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.) Full financial aid is available for all applications (even late) and admissions is need-blind.

Admissions are only done to ensure students have sufficient mathematical background and writing ability (due to sheer number of students, there is no “grading”), understand English, and are able to learn from Evan-style writing. In particular, admissions is not a merit-based competition. See the application PDF for more details.
