Version A is the explanation of knowledge points and the addition of exercises.

Version b has no knowledge points to explain, only exercises.

2, the difficulty is different:

Version a is mainly about the introduction of problems, and version a is simpler than version B. B version is all after-school exercises, and B version is more difficult than A version.

3. Use different methods:

Version A is equivalent to a textbook, learning one topic every week, 5 knowledge points every week, and learning all the topics in 40 weeks.

Version B is equivalent to a weekend exam, which consolidates and summarizes knowledge points and integrates various topics to achieve overall improvement through problems and mistakes encountered in the process of answering questions.

Extended data:

1, the purpose of the international mathematical Olympics:

Stimulate teenagers' mathematical ability; Stimulate young people's interest in mathematics; Discover the reserve army of scientific and technological talents; Promote the exchange and development of mathematics education in various countries.

2, the international mathematical olympiad held time:

It is held once a year in July.

3. Organizer of the International Mathematical Olympiad:

It is hosted by participating countries in turn, and the funds are provided by the host country.

4. Participants in the International Mathematical Olympiad:

The contestants are middle school students, each team has 6 people, and 2 mathematicians are sent as the team leader.

5. International Mathematical Olympiad Examination Questions:

The test questions were provided by the participating countries, then selected by the host country and submitted to the examiners' committee for voting, resulting in six test questions. The host country does not provide test questions. After the test questions are determined, they will be written in English, French, German, Russian and other working languages, and the team leader will translate them into the national language.

6. International Mathematical Olympiad Examination:

The exam is divided into two days, 4.5 hours a day, and three questions are tested.

Six players from the same team were assigned to six different examination rooms to answer questions independently. The answer sheet will be judged by the national team leader and then negotiated with the coordinator designated by the organizer. If there is any objection, it will be submitted to the examiner's Committee for arbitration. 7 points for each question, out of 42 points.

7. International Mathematical Olympiad Awards:

There are first prize (gold medal), second prize (silver medal) and third prize (bronze medal) in the competition, and the ratio is roughly1:2: 3; About half of the contestants won the prize. The award criteria of each session are related to the results of the current exam.
