No, according to the enrollment brochure issued by Zhejiang Normal University in 2023, the admission principle of Zhejiang Normal University is to give priority to the total score, and there is no grade difference between majors. Professional grade difference refers to the difference in scores when enrolling non-first professional volunteer candidates. For example, a school stipulates a professional grade difference of 4 points. When the school assigns majors, it subtracts 4 points from the scores of candidates who volunteer to fill in the second major, and determines the major with the rankings of candidates who volunteer to fill in the first major.
