It depends on your city, the level and class hours of the summer class you choose, and so on. Tell me about my situation for your reference: The first training organized by our school in the summer vacation (20 14) is competition literacy training, which lasts for six days and has eight classes every day (calculated as 45 minutes per class). The cost is 1300 yuan/person, and our school invited us to enter the top 100 education schools in Beijing. The other time was held in Jinan Branch of Beijing Education University on 20 15, with seven days and ten classes every day. It costs 2000 yuan, including accommodation and breakfast (but the hotel is not very good). Teachers are professors from Nantah and Hunan University, and sophomores from the Institute of Biological Sciences of Peking University won prizes in the competition (mostly at the national level). The school is relatively small, so it is cheaper. Looking at it now, it is estimated that the relevant training fees will be raised a little. In some places where the school sites in second-tier cities are relatively biased, it is estimated that it is more reliable to charge 3,000-5,000 yuan for seven days.
But to tell the truth, it is basically useless to rely on teacher training for such a thing as biology competition. The key is to recite it yourself. Finally, I wish my brother (let's just say you took part in the competition, there is this problem) a smooth competition and a good exam.
