I just graduated this year and majored in computer science. I think it is more appropriate to buy it in my junior year. When I was a freshman and a sophomore, I basically learned some basic theoretical knowledge and some small programming, which was basically enough in the computer room. When I was a junior, I began to fully contact the professional knowledge of computers. At this time, I had a computer, and this is what I learned. In my senior year, I got a job. But don't forget, I graduated once in my last senior year of computer science. There is basically only one dormitory for freshmen and sophomores in our class. By junior year, basically everyone will have a dormitory, including girls, so I suggest you buy it in junior year. At that time, it was more practical and the key was that we studied computers, and the software we used would become bigger and bigger. After two or three years, you will find it very difficult to run the software at that time.
