Therefore, unless undergraduates are particularly excellent, I am afraid it is difficult to publish papers in such free journals, and in most cases, they still have to invest in those paid journals. Of course, it doesn't mean that other charges will be bad. Many paid periodicals are also very good. Even if you have money, people may not send it to you, but it depends on whether your paper is well written.

If undergraduates want to publish general journals and publish them quickly, they can choose a relatively good one among the paid journals, which is the most efficient method.
