Studymode is an American paper periodical website, from which you can learn some papers to supplement yourself. When we study in China, we have to double-check all our papers, and only when the double-check rate is low can we pass, so we can find some materials from foreign websites for our convenience and not to be double-checked. You can learn from it, but you can't just write a paper by some partial methods. You should have real materials, remember that academics can't be faked, and take academics seriously.
