For the elective course of Northeast Forestry University, if the public elective course has more than one point (the lowest score is 6, I chose 7 points), can the professional elective course have less than one point? Look at your training plan (a book). There is a difference between the total credits of elective courses and at least the number of elective courses. The difference is that you can choose both elective courses and public courses. For example, our major requires "40 credits for elective courses, including at least 30 credits for professional elective courses and at least 6 credits for public elective courses". Then these four credits are the points where you can choose both elective courses and public elective courses. I hope it helps you.
