You can buy a computer if you can at home, because this major is still very close to computers. General colleges and universities will offer some computer-related courses, such as web design, FLASH, 3D MAX, Photoshop, C language, VB language, database, data structure, computing network technology, multimedia technology and so on. These courses are closely related to computers, and autonomous learning is advocated in university study. With a computer, you can search for knowledge you are interested in and study, but computers also have shortcomings. Don't indulge in games and videos, or you will lose yourself. . . I hope it helps you.
