I have a niece, 15 years old. Her academic performance is not very good. She graduated from junior high school and wants to study vocational high school technology. I don't know what major to study. Ask for help Learning technology in vocational schools is beneficial to students with poor grades, and better employment opportunities can be obtained by mastering skills. Generally, there are many majors that can be learned in technical schools, such as image design, preschool education, e-commerce, high-speed rail crew, West Point baking, tourism management, West Point western food, and new media operation.
