Putuo District is a depression of educational resources, and the only one qualified to stand in the forest of famous schools is Caoyang No. 2 Middle School. In 2014, it won the top six independent enrollment quotas of Tsinghua University and Peking University in Shanghai, the largest number of Fudan Boya Experience Camps in China, and became the student source base of Tsinghua University's New Centennial Leading Talent Program, the model school of Tongji University's nursery base, and the first batch of pilot schools of the "International Economic Plan" of Shanghai Foreign University. In addition to the well-known German classes that do not participate in domestic enrollment, Cao Er's compound rate in recent years has been stable at 6%, and the admission rate of 211 nine schools is about 11%, but the number of students in Qingbei is about 4-6 per session, these data cannot represent the whereabouts of all outstanding students, but it can still be seen that although Cao Er is not defeated by the first echelon of strong schools, it is still indisputable to sit in the middle seat of the traditional eight universities in the second echelon.

Cao Er's language classes are the key partners of the Tongji Sowers Program, and currently offers German, Italian and Dutch science and engineering experimental classes, with 10 additional language courses per week in each class, and at the same time, the pace is the same as that of the science class, which is fast and stressful. Among them, there are many years of successful experience in the German class, every day at noon according to the German teacher's schedule to go to the German office to do a German corner, with the teacher or German exchange students to practice dialogue, the semester also has Christmas party, Easter egg painting, German month, German sketches and other activities, the first year of high school also has a month of study tour in Germany. However, in terms of clubs, except for the German club for mandatory participation, other clubs rarely see the figure of German class students, lack of time is the main reason, German class students start reading early from 6:40 in the morning, plus classes until 20:00, not counting the time to complete homework, the whole day is almost full, no energy to participate in more activities unrelated to schoolwork. The German class implements a mobility system, and students who do not choose physics or chemistry but are interested in liberal arts will also be placed out of the German Polytechnic experimental class, and only enter and exit. After three years of German study, students can obtain DSD certificates of different levels, and most of them enter the top 20 universities in Germany for further study with reference to the results of the Chinese college entrance examination, and have been ranked first among the 44 schools that carry out DSD courses in the country. A small number of them stayed in China and entered 211 and 985 universities, and because of the cooperative relationship, Tongji University is the choice of many students who stay abroad.

Cao Er also set up a liberal arts and sciences comprehensive experimental class and a Houzhi science and technology experimental class, the former was named after Fudan's liberal arts cup, and later transformed into a science and engineering class that strives for the college entrance examination admission rate; The latter mainly fights for competitions. The learning pressure of the two classes is roughly the same as that of the language experimental class, the first year of high school is running forward according to the schedule of the third year of high school, and the homework is twice that of the parallel class, and there are no club classes and psychology classes, and even physical exercise classes will be canceled, but the corresponding educational resources are better, and there are more training and lectures.

Cao Er's club activities are in vain, only the day of recruitment is the most lively, bicycle club, street dance club, Shanghai club, simulated CPPCC club, photography club, etc., but it is difficult to organize activities after joining the club, and the participants are only in single digits each time, one of the main reasons is that they are busy with their studies.

There are toilets and air conditioning indoors, and Cao Er's dormitory environment is not bad, but the bathroom is still one on each floor, there are about 15 positions, and there are no curtains and lockers in the bathroom. There are 4 people in the dormitory, and the table is larger than the bed, and you may have to curl up and sleep over 1.8 meters. There are power outlets and telephones in the dormitory, and calls can only be made in and not out. At 23:00 in the evening, the dormitory manager came back to check the room, if he found that he turned on the flashlight, he would knock on the door and deduct disciplinary points, and he may be removed from the dormitory if he violated discipline more than four times. Cao Er's canteen food is extremely ordinary, with only one type of breakfast served every day, with a certain kind of dim sum and some kind of porridge as standard, and some seasonal foods such as zongzi and Qingtuan will be served every week when they eat noodles or wontons. Lunch and dinner are also very small, and most students choose to eat on campus or at convenience stores.

Cao Yang's score line is about 18-25 in the city, but the score rate can enter the top 15, which is a typical model of strict teachers and high apprentices. Experimental classes, especially German classes, are mostly self-recruited, recommended and zero-volunteered. Cao Er's self-recruitment ticket has requirements for the first and second model scores, the mathematics in the test questions is the difficulty of the competition, there are a large number of college entrance examination vocabulary in English, and the scope of physics examination is relatively wide, and the questions may be asked in English.
