The difficulty of reading the test paper was 148 first prize last year, and this year it seems to be more than 150. The score of the second prize is about 8 or 9 points lower than that of the first prize.

Since modern times, mathematical competition has become one of the effective means to explore mathematical talents. Mathematics competition in the modern sense began in Hungary. Most of the winners of some major math competitions have made great achievements in their later careers. Therefore, all developed countries in the world attach great importance to mathematics competitions.

Related information introduction:

Under normal circumstances, the relevant state departments will organize all kinds of mathematics competitions at all levels (such as the above competitions). First, primary elections will be held in various schools, then county (district), city and province will be selected, and finally national examinations will be held.

If a person can finally stand out from the national competition and achieve excellent results, then such a person will have the opportunity to participate in the highest-level International Mathematical Olympiad (IMO).

Therefore, we can regard the mathematics competition of each country as the selection test of the International Mathematical Olympiad (IMO). Any math enthusiast or math contest player is proud to participate in IMO, and the player who can win the trophy will naturally receive key training after returning home.
