I want to publish a paper during my college years. Can I choose a topic at will?
Of course, you can choose any topic when you publish a paper in a university. As long as you think you can finish it, it is your freedom to choose any topic and direction. When submitting a paper, it depends on what major you are writing, and then choose the corresponding sci-tech journal of this major. There are many sci-tech periodicals, and different sci-tech periodicals publish different types of papers.
