I wonder which school your junior high school is in?
In 2007, my child was admitted to the city class of the middle school of the province from the middle school of the province.
I also won the first prize in the Guangdong Biology Competition that year.
There are four experimental classes in junior high school and senior high school: two municipal classes and two provincial classes. The best class 1 in junior high school and the best class 3 in senior high school belong to the city class, and science, especially mathematics, can only enter before the score. There is no significant difference between the other three experimental classes, but the difference between the experimental class and the ordinary class is quite large. Generally speaking, most of the top 50 students are from the best class, and the top 100 students are almost from the experimental class.
Good luck!
