The college entrance examination preparation for college entrance examination students began long before entering the third and ninth grades of senior high school. The first step in planning is to carefully plan your four-year senior high school curriculum. American high schools offer one or two hundred courses, many of which are optional courses, and students have a wide range of choices in compulsory subjects. The same course has several different levels and different difficulties. As a student who wants to enter a university, especially a first-and second-rate university, it is very important to choose courses for four years. The most direct reason is that American universities attach great importance to candidates' four-year high school courses, and it is difficult and challenging to choose courses, so as to infer candidates' foundation and future university learning potential. In the application form for students to apply for universities, high school student counselors should fill in the challenge index of students' four-year courses according to the courses they have taken. On the other hand, the selected courses are difficult (AP courses, IB courses or honorary courses) and have high credits. What kind of courses students take directly affects GPA credits, and GPA credits for four years in high school are an important reference index for university admission. Generally speaking, American high school students who aim at first-and second-tier universities will choose as many difficult courses as possible, and elective courses will also reflect their interests as much as possible or be linked to the majors they may choose in the future. Secondly, because American universities attach great importance to students' performance in and out of the classroom, interested students and parents will also arrange extracurricular activities for four years in high school reasonably. There are many kinds of organizations in American high schools. Students participate voluntarily according to their hobbies. Students who want to show their leadership skills can submit a "letter of intent" to the school and set up a new club. However, there are many student organizations that not everyone can apply for, such as the Student Union (elected), the National Honorary Society (recommended by teachers and actively participating in volunteer activities), and of course there are various ones. After four years of unremitting extracurricular activities that can show their talents, community service activities also account for a very heavy weight in the process of applying for universities. The summer vacation after grade nine (or even before grade nine) must not be wasted. There are many choices for American high school students in their summer vacation: attending summer school, taking a class in advance, participating in various summer camps, scientific research plans, course studies organized by American universities, attending SAT cram schools, working, and participating in various volunteer activities. Accumulate community service time, etc. No student wants to make full use of the summer vacation to add luster to himself on the college entrance examination application form. The real university application should start from the summer vacation after the eleventh grade. The eleventh grade of American high school students is the busiest year for study and various activities. Many high school students who are going to take the college entrance examination have completed all the courses required for high school graduation this year and have understood their own strength. Most students began to seriously consider the universities they want to apply for or can apply for in this year. Most students completed SAT I or/and ACT in the eleventh grade. After taking the SAT (Professional Exam) for more than three times, they passed the AP exam as much as possible, began to know more about the universities they were interested in, made campus visits, and began to consider applying for scholarships. Some students and parents began to prepare college application materials in the summer vacation of the eleventh grade and began to apply for college application compositions by hand. American high school students can apply to many universities, some students apply to ten or more universities, and each university needs a lot of application materials, so the application process will be very complicated and nerve-racking. There are many universities in the United States with different styles. Senior high school counselors generally advise parents to take their students to interested schools for a campus visit, visit university campuses and observe them on the spot to determine whether they like them or not. To prepare for an interview with the University Admissions Department (a very important level), there are generally three types of schools to apply for: Gundam, (higher than one's own strength), accessible/safe schools comparable to one's own strength, and guaranteed backup schools. Many American universities have early admission (early action or early decision), and students who decide to give it a try usually send all the application materials in 10 or10/month of grade 12. Even if they don't apply in advance, most first-and second-rate American universities begin to publish their lists at the end of March each year. (Please do not reprint, offenders will be prosecuted)
