About International Olympiads of Mathematics

The International Olympiad of Mathematics, a test of competence and proficiency in Mathematics, is held annually at the national and international levels based on syllabus prescribed by CBSE/ICSE and the State Boards. Apart from syllabus, a part of test paper is based on mental ability and reasoning.

A student between class 1st to 12th can participate in iOM’11 through his/her school only. The language medium is English only. The examination is being conducted for all classes from 1st to 12th with the following details:

For Classes 1-2 :There will be 30 questions and the duration will be of 60 Minutes.

For Classes 3-12 : For Classes 3-12: There will be 40 questions and the duration will be of 40 to 60 Minutes.*

*Time Division

Participants from Class 3rd to 12th will be required to complete the test between a minimum of 40 minutes and a maximum of 60 minutes. Answer sheets cannot be submitted before the completion of 40 minutes. Participants should try to submit the answer sheet, with maximum correct answers, at the earliest after the end of 40 minutes to get the benefit of the third tie-breaker** rule. The invigilator is expected to write the correct time in the appropriate space provided in the answer sheet. As time is the third, not the first/second tie-breaker rule, students are requested to focus on achieving maximum correct answers in an optimum time.


Each question may not carry the same mark. In case of tie-up, preference will be given to the student who has attempted a greater number of questions correctly. The second preference will be given to following respect: First Mathematics related question and then mental ability and reasoning. The third preference will be given to the student, who has submitted the answer sheet earlier than the others. Should the tie-up still exist, a telephonic interview will be conducted with the participant.
