In China, the period of high school is very important for students, they will go to college after finishing high school. Because there are so many students in our country, the students have to take the college entrance exam, the test will decide which school they should go to. Every student in high school will study many course, when the second year comes, students will choose some courses for the college entrance exam. The first thing they should pay attention to is to measure what subject they are good at. Some students are good at math and geography, these students are always weak in politics, then they should keep on learning science. Some students are good at Chinese and English, they should choose to study art. What if the students are good at both? I will advise them to learn the course they are interested.
