• The Math League Organizing Committee reserves the right to adjust the question-setting mechanism as needed.

• Preliminary Certificates — Certificates will be awarded proportionally based on students’ performance:
  • "Honor Roll of Distinction Certificate Top 8%": awarded to students who rank in the top 8% of their grade.
  • "Honor Roll Certificate Top 25%": awarded to students who rank in the top 25% of their grade.
  • "Certificate of Achievement Top 50%": awarded to students who rank in the top 50% of their grade.
  • "Certificate of Participation": awarded to all other participants.
• Students who win certificates in the preliminary round will receive an official certificate issued by the Math League. The list of winners will be announced on the official American website of the Math League (www.mathleague.com).
• The results of the Math League can serve as an important reference when applying to well-known high schools and universities in North America.
• Students in grades 1 to 10 who receive an "Honor Roll of Distinction Certificate — Top 8%", "Honor Roll Certificate — Top 25%", or "Certificate of Achievement — Top 50%" in the preliminary round are eligible to participate in the semi-final.
• Grades 8 and 9 use the same test paper. When determining eligibility, all students from grades 8 and 9 are ranked together by score; they are not compared separately by grade. The certificate will indicate the grade group in which the student participated. The same selection process applies to the high school group.

After the preliminary round, each participating student will receive the following analysis and targeted review materials:

• National preliminary results statistics, including a normal distribution graph of scores, average score, standard deviation, and other relevant data.
• Individual student score report, detailing whether each question was answered correctly, the knowledge points tested, and the difficulty level of each question.
• Targeted review questions (for students in grades 3–12): Custom practice questions are generated based on each student’s preliminary exam paper to help address their specific weaknesses.

• Equipment required for online activity: Students should use a laptop or tablet with a camera, as well as a smartphone with a camera and microphone, to participate in the preliminary round and answer questions online through a web browser. The entire answering process will be monitored and recorded in real time to ensure fairness and integrity. The use of any instant messaging tools (e.g., WeChat) is strictly prohibited.
