• Are the questions in English?
  Yes, all questions in every round are in English. You may use a non-electronic dictionary.
• Besides a non-electronic dictionary, what else is allowed during CTMC?
  Each participant may use a scientific calculator for the Individual and Relay Rounds. Calculators are not permitted during the Team Round. An explanation of the three rounds can be found in Section B regarding the Competition Format.

CTMC Participants

CTMC is a team-based competition for high school students, with 6 members per team. A team can be a mix of students from grades 10, 11, or 12. Team members from grade 9 are also allowed, but it is recommended to have at least one senior student. Every member must be present on the competition day to have a chance of winning.

FAQ

• Can participants be from different schools?
  At UNPAR, all participants can be from the same school or a combination of different schools. Teams can choose their own name, provided it is appropriate. The school address can be filled in with the names of each participant’s school.
• Can one school send more than one team?
  Yes, each school can send more than one team. At UNPAR, there is no limit to the number of teams a single school can register. The supervising teacher may be the same for multiple teams.

B. Competition Format

Individual Round

• Each participant works individually.
• There are 10 short-answer questions.
• Calculators are permitted.
• Duration: 45 minutes.

Team Round

• All members of the same team can collaborate and strategize.
• There are 25 short-answer questions.
• Calculators are not permitted.
• Duration: 45 minutes.

Relay Round

• Each team is divided into two small groups of 3 people each, denoted as 1a, 1b, 1c, and 2a, 2b, 2c.
• Participants work separately. The answer from participant ‘a’ becomes the basis for participant ‘b’ to answer their question. Similarly, the answer from ‘b’ is needed by ‘c’ to answer theirs. Participant ‘c’ will write the final answer on the sheet provided by the committee.
• The flow of answers is only from ‘a’ to ‘b’ to ‘c’, not the other way around.
  
  
• Participants a, b, and c can work on their respective questions simultaneously. However, ‘b’ needs the answer from ‘a’, and ‘c’ needs the answer from ‘b’.
  • Participants 1a, 1b, 2a, or 2b can correct their answers and pass them to the next person, as long as time permits.
  • The time available is 8 minutes per relay.
  • Calculators are permitted.
  • In each relay, during the first 4 minutes, participants 1c and 2c are advised to fill in their answers in the “early answer” column, which has the potential for maximum points, but it can be left blank (The committee will mark the blank answer).
  • In the second 4 minutes, participants 1c and 2c are only allowed to fill in their answers in the “final answer” column.
  • There are three sets of questions (relays), each with the same rules.
  • Relay round answer sheet template provided only to participants 1c and 2c:
