And today the plan is picturesque to go into.

Won the third prize in the preliminary round of the Chemistry OlympiadSelf-enrollmentis useful.

The awards and specialties won by students are explained as follows:

Chinese Chemistry Olympiad.

The prizes of the preliminary round are the provincial first prize, the provincial second prize and the provincial third prize, and the awards of the Chinese Chemistry Olympiad (final) are the national first prize, the national second prize and the national third prize.

When applying for some universities, you can directly pass the preliminary examination to obtain the qualification for self-recruitment. Only by virtue of obtaining the provincial two provinces and three good such as stoves, it will not obtain the self-recruitment qualification of Tsinghua University and Peking University and other first-class universities.

International Chemistry Olympiad(icho)

It is the world's largest and most influential chemistry competition for middle school students. It originated in Czechoslovakia.

Since the first competition was held in the Czech Republic in 1968, it has been held annually except for a one-year hiatus in 1971. Only three countries participated in the first ICHO competition, but the number of participating countries has increased since then, and now there are more than 80 countries and regions.

Participate in this activity.

It depends on the difficulty of the paper.

The chemistry competition paper is very difficult, and the highest score in Jiangsu is only 69 points, and one of the 45 points won the provincial first prize. Last year, the paper was relatively easy, and saving more than 60 points was the first prize. Recommendations:

Last year, I took the chemistry balance test, which I haven't taken for several years, and it scored more than 10 points. It may still be taken this year. In recent years, inference questions have accounted for more than half of the papers.

The complexes of the previous year were a bit difficult, but last year's was not difficult, but as long as the foundation is solid, you should be able to get most or all of the points. Organic is a giveaway. Crystals are more difficult, and the structure diagram can be placed last.

It depends on the difficulty of the paper. According to the provinces, it is generally a preliminary competition in the city, then a preliminary selection in the province, and then a preliminary round in the national high school chemistry competition, and then a provincial team selection after passing the national final, and then a winter camp.

The difficulty of the chemistry competition is much more difficult than the ordinary college entrance examination, and the amount of learning is too large for most high school students. After years of evolution, discipline competitions are now a very effective tool for selecting talents.

Purpose of the competition:

1. Popularize the knowledge of chemistry, encourage young people to get in touch with the frontier of chemistry development, understand the significance of chemistry to science and technology, social economy and people's lives, and learn the ideological methods and working methods of chemists, so as to stimulate their interest and creative spirit in learning chemistry.

2. Explore the ideas, methods and ways to discover and cultivate outstanding talents at an early stage.

3. Promote the exchange of new ideas and methods of chemistry teaching, promote the reform of chemistry teaching in universities and middle schools, and improve the level of chemistry teaching in China.

4. Select the contestants to participate in the annual international chemistry competition. All activities and publicity related to the Contest shall be consistent with the purpose of the Contest.

You can add 10 to 30 points for the college entrance examination or high school entrance examination, and you can add 10 points for the above ones!

The purpose of the activity is to implement the spirit of the new curriculum reform, advocate research-based learning, and encourage innovation and practice.

The purpose of the activity is to build a platform for the majority of young people to demonstrate their learning ability and innovative practice ability, help innovative talents stand out, provide an effective basis for colleges and universities to independently select talents, and assist young people with innovative practice ability to succeed.

Categories: 1. Mathematics: Junior 1, 2, 3, 2, 2, 2, Physics: 3 Group, 1 Group, 2 Group.

3. Chemistry: Senior 1 and 2.

Meaning: Eligible to take the independent entrance examination.

To be honest, it doesn't mean anything, you can only add a touch to your resume.

The National Middle School Students' Mathematics, Physics and Chemistry Specialty Competition is held by giants, and after the preliminary examination, the first, second, third prizes and excellence awards will be divided according to the proportional line (that is, you are eligible to pay **), and then let these people pay ** (similar to **sex learning), and then decide who can enter the finals (the first and second prizes can be passed casually, and the third prize can be passed seriously). After telling you that you have entered the finals, you will be asked to pay money to participate in what training camp or something, and the so-called national first, second and third prizes will be determined in the training camp.

I also won the first prize in physics, chemistry and mathematics in the preliminary competition, and I made thousands of friends in physics and chemistry to participate in the training, but I decided not to go.

The landlord, you won the second prize, which means that these two sciences are good, but this certificate is really useless, at most you can add an attachment when applying for independent enrollment and applying for Hong Kong schools, and it is not as some people say that you can get independent enrollment places or even direct promotion places, this is really not.

I think if you are good at math, you can work the mathematical modeling competition, which still has a certain gold content.

The sophomore in high school is not easy, I won the first prize in mathematics, and this year's questions are much easier than last year.

means you qualify for the finals

How much did you score in math???

What's the deal with physics and chemistry being the same?

Divide 1200 by 4 to get 300, and (1200-300) by (90-70) to get 45

A sees B 45 minutes after entering.

The answer is 16 minutes and 40 seconds The circumference of the square wall is 1200 meters, so its variable length is 1200 4 = 300 meters.

A and B are in two opposite corners before departure, so at this time A and B are 300 + 300 = 600 meters apart.

When A is 300 meters away from B, A is likely to see B. Suppose that after x minutes, the distance to B is 300 meters:

90x=70x+300 ===>x=15 (minutes).

After 15 minutes, A may see B, provided that A and B are on one side.

Then after 15 minutes, A has walked 15 90 = 1350 meters, and B has walked 15 70 = 1050 meters.

At this point, A is still 1500-1350=150 meters away from the next corner.

In other words, it takes 150 90 = 5 3 minutes = 1 minute and 40 seconds for A to pass through this corner.

At this point, B has walked 70 5 3 = meters, and there are still meters left on the next corner.

So at this time, A can already see B, then A needs to spend a total of 15 + 1 minute and 40 seconds = 16 minutes and 40 seconds.
