There is no specific requirement standard for this problem. Usually, each school has different requirements. Some may require one or two articles, while others require about three or five articles, so the details also depend on the regulations of the author's school.
Tsinghua University's four SCI articles have no requirements for IF, and different research groups have different graduation requirements. The general tutor requires a special master's degree and also sends SCI papers.

Beijing Normal University (College of Nuclear Science and Technology) directly wrote an SCI and a core, and took an SCI test.
More than one SCI in Sichuan University
Generally speaking, it is enough to prepare 2-3 doctoral papers, but the writing of SCI papers is quite difficult and requires considerable time and energy. Is there a writing format template for SCI journals? Of course there is. If you don't know how to write, you can read more. The template of the paper is almost universal. It is a good choice to start with imitation.
