A province can enter the provincial team in the math competition. Algebra has a basic level (assuming I have studied systematically but haven't brushed the questions). If you do more questions, you can do it slowly and steadily. 92+ 2 equals 80. This is unstable. I joined the provincial team myself, and I joined the provincial team in my sophomore year. What is weak and difficult is not how to enter the provincial team, but how to get on the card.
