## Competition Information

What follows is information on the competition's format and also general information pertaining to the 2008 Math Challengers competition as a whole. Please read this information carefully

### Competition Format

The competition consists of 4 stages. Stage 1 ("Blitz") and Stage 2 ("Bull's Eye") are individual competitions. Stage 3 ("Co-op") is a Team competition. Stage 4 ("Face-Off") is a one-on-one competition between the top 10 individuals who participated in stages 1 and 2.

Individual Score
The maximum possible individual score is 50.
Team Score
The maximum possible team score is 70. The team score is calculated in the following way: The average of the top 4 entries per team + the score of the team from the Co-op stage of the competition.

Average
The above mentioned team average will be calculated by taking into account the marks of the best four individual participants out of the up to five scores of the individuals of that team.
(NOTE: if a team consists of less than 4 individuals, scores of 0 will be used for any individual missing and will be included in the calculation of the team's average (for example if a team has only 3 participants who scored 50, 40, and 30, and if they scored 18 in the Co-op stage, then their final team score will be (50+40+30+0)/4+18=48.)

Awards and Provincial Finals
The top 4 schools in each of the competitions (if more than 5 schools participate) will be awarded trophies. The top 3 individuals in each of the competitions (Based on their score before the Face-Off stage) will be awarded trophies. The top 10 individuals (but no more than 5 individuals of the same grade from any one school), or the top 25% of participants, (whichever is less), in each of the competitions will advance to the Face-Off stage and will be awarded medals. All individual final standings are based on the performance in the Blitz and Bull's Eye stages. Additional awards or prizes will be awarded to the best performers of the Face-Off stage. The top 4 schools (or more based on performance) participating in any of the Regional pools will be invited to participate in the Provincial finals. Also, all individuals participating in any of the Regional pools Face-Off stage will be separately invited to participate in the Provincial finals in the event that their school do not qualify a team. At the Provincial finals, the top schools and top individuals will be awarded trophies and/or medals. Some of the top individuals in the grade 8 competition will be invited to participate in an international competition (Intramurals).

### General Instructions

For the 2010 Competition | Also see Instructions to Competitors and MC's

1. The use of notes or any other reference material is not permitted.
2. Calculators are not permitted for the Bull's-Eye, Blitz or Face-Off rounds, however scientific calculators are permitted only for the co-op round. Graphics calculators and programmable calculators are not allowed at all. Devices with wireless communication capabilities are absolutely not allowed.
3. Scrap paper WILL NOT be provided for the first two individual stages and MUST NOT be used. The participants are expected to do all their computations and writing on the competition papers. They may write wherever they want on the paper except for the clearly marked area where they must write the final answers to the questions.
4. Participants are not allowed to ask any questions during any of the stages of the contest. Invigilators are instructed not to answer any questions.
5. If a participant has to leave the room (for any reason), during any of the stages, he/she may only be allowed to come back into the room after that stage is finished.
6. Participants must write their answers to any of the questions in the designated area. The markers will not look for the answers anywhere else on the sheet. The written answer must be clear and in a legible and acceptable format. If an answer is dubious or if the markers cannot clearly read an answer, they will mark it as incorrect.
7. Units are NOT needed, and the participants are strongly urged NOT to provide any units in their answers to any of the questions. We will attempt to include the correct units (where appropriate) in the designated area on the answer sheet. BUT, if a participant provides units (for whatever reason), they MUST be correct, and exactly as asked in the question. Otherwise, the answer will be counted as incorrect.
8. All answers must be expressed in the simplest form (unless otherwise specified). The simplest form (unless the answer is an expression or a radical that can not be simplified any further) is usually an integer or a common fraction that cannot be simplified any further. If a common fraction can be simplified further into an integer then the answer must be provided in an integer format. .An exception is for questions with monetary units where the answers (unless otherwise specified) must be provided as decimal expression. Also some questions require that the answer be provided correct to a certain number of decimal places and the answer must be provided exactly as specified.
