*N2K is a math competition for students between the ages of 9 and 14. The cut-off date for all 14-year-old students in June 15th of each competition year. If a student will be turning 15 before this date during the same year as the competition, the student will not be eligible to participate in the competition.N2K is only open to U.S. Citizens living within the United States and to children of military personnel living abroad. No international students are eligible at this time.
**We appreciate your kindness and desire to share good things, but please do not share the proprietary information you receive through your Prime membership. As a support of N2K, you have purchased the benefit of advanced preparation for your students, and it defeats the purpose if one person decides to make the advantage public. We are operating under the honor code and hope you will heed our request. If the advantages become public, we will have to spend additional funds to keep them proprietary and the benefit of the entire competition becomes at risk.
