The international chemistry olympiad among schoolchildren will help 9 grade students to delve a little more in to the study of the subject. We advise all participants to do the test tasks with answers first that are similar to the real tasks of the olympiad. This will allow the student to prepare better and to start passing the olympiad more confidently in the future. If the student will be the winner at the regional level, he will be invited to the “One hundred points” competition which participants receive additional points when applying to universities.
