Hi everyone!

As we gear up for another exciting school year, what better way to kick things off than with a DMOJ contest? With that, we present the Back to School '24 contest!

The contest will take place from Saturday, August 31st to Sunday, September 8th. Participants will have a 3-hour window to complete 6 problems.

The contest is rated for all users with a rating less than 2400.

For more information, please visit the contest page.

Good luck and have fun!

Hi everyone,

We are proud to present the 2024 Spring Coding Bowl: a 2-hour, 5-problem competition open to all high school students. The contest will run from April 26th 00:00 EDT to April 29th 00:00 EDT (Eastern Daylight Time), and the problems will range in difficulty from beginner to intermediate.

To register, please join the Spring Coding Bowl organization here. You must register to participate. The contest will be hosted here on DMOJ. Please ensure that you register before April 26th.

An official honour roll will be published on the contest page, the top scorers will be named as "Coders of the Year", and schools will be ranked by the sum of the three highest scores from each school. As such, please be sure to tell other students in your school to participate (perhaps get your school's coding club involved)!

If you would like to prepare, you can try to solve last year's problems here on DMOJ.

Finally, this year we are also offering cash prizes and an opportunity to enter a raffle for all eligible high school students! Please check the contest page for more details.

Good luck to all participants!
