Subject Challenge Participation

What are they?

The Caribou Subject Challenges are a new addition to the Caribou site. They are contests of different subjects that will take place throughout the year, in addition to the Caribou Mathematics Cup. Some examples include the Coding Contest and a new Calcrostics Contest.

How many are there?

There will be four Subject Challenges in a school year. They will usually be run on the months that don't have a Caribou Mathematics Contest. That is, September, December, March, and June.

Are they related to the Caribou Cup?

They are not related to the Caribou Cup. The Caribou Cup only consists of the six Mathematics Contests that run throughout a school year. These Subject Challenges will have a similar format, but they will not affect a student's score in the Caribou Cup.

Who can take the Subject Challenges?

Any school-aged student is allowed to participate in the Subject Challenges. The Calcrostics Contest is categorized into grades like the Mathematics contests where a student can participate in their level or a higher level. The Coding Contest is offered with different difficulty levels (Junior and Senior) and a student can choose the level they desire. Students can even choose to do more than one Coding Contest that is offered on a given day if they're up for it!

How are the Subject Challenges paid for?

The new Subject Challenges will adopt the "Non-Math Credits" system. In this system, a student/teacher/parent can purchase these Non-Math Credits. Each challenge will cost 1 credit, and a student will be given access to a challenge if they have an unused credit. Additionally, there is a "School Wide Non-Math Pass" which will give all students of a school access to all the Subject Challenges during a Caribou year (July to June).

How can a student register for the Subject Challenges?

An access code is needed to participate. Additionally, a student must have an unused Non-Math Credit to participate in one of the Subject Challenges. For information on how to register, please visit the Registration Guide.

Upcoming Coding Contests

Student can start the contest on either contest day from 12:00 AM EST of the first day to 11:59 PM EST of the second day. The student MUST use an access code with Non-Math Contest access and log in to the Caribou Coding Contest Site to start the contest. Once begun, the student has 120 consecutive minutes to complete the test. Be sure to start the contest at least 2 hours before the contest end time to give yourself enough time to complete the contest!
