Choosing college major has been the most important thing for both children and their parents, because it has a big influence on a chid's future development. I have even heard someone who got the highest score in college entrance exams. but giving up their college life due to the majors which they really didn't like. They spent one more year studying to choose other majors which they liked. So, for students, studying hard is not their only mission to finish. They must know more about their hobbies, career planning and their academic achievements that eventually help them choose correct majors. On the other hand, it's hard to gain enough infotmation about future career fileds and a variety of colleges and majors for students and their parents. So, more and more students and parents become anxious about choosing college major. In that case, someone who are professional on career planning help students to choose correct major. Of course, it's rechargeable. However, after they successfully helped more and more students choose correct majors, more and more parents also learned how to choose colleges and majors for their children, becauser the professionals posted a massive of videos online. So, new problems are coming. The amount of excellent students who apply for the same great major is more than the numbers of being matriculated.
