Now the provinces organize their own preliminaries, determine their own names for the semi-finals, and then conduct the semi-finals at a unified time throughout the country. It is divided into two attempts, with 64 points for eight fill-in-the-blank questions and 56 points for three major questions. The difficulty is slightly higher than that of the college entrance examination. Try four major questions for the second time, 40 points for plane geometry, 40 points for number theory, 50 points for inequality and 50 points for combination. Try 80 minutes, try 150 minutes. The second exam requires a lot of extra-curricular knowledge and is relatively difficult. You can't do it without learning the Olympic math, but the difficulty of the Olympic math problem is moderate.

Shandong's score is about 160, so you can win the first prize, and the second grade is 100+.

There is another problem. I want to take part in this year's competition, but I can't seem to catch up. I have the impression that the preliminary registration in Shandong has ended. Shandong preliminaries took the exam earlier.
