Missed the preliminary contest of 20 13 Jiangsu Senior High School Mathematics League. Do you still have a chance to attend? Can I participate in the semi-finals? I'm about to be promoted to the third grade, 10 is in the league. I don't think you took part in the preliminary contest in Jiangsu Province. . . Guangdong Chemistry Competition expressed curiosity. . . . If you miss the preliminaries, you are not qualified to participate in the semi-finals in theory if you don't want some grey ways, because the semi-finals are much stricter than the preliminaries. You can find some relevant teachers and see if you can get some indicators of people who don't want to go, and then you can change your name.
