I passed, but it also requires personal efforts. I studied hard during that time. I went to work during the day and went to class at night, and I didn't waste any time. And I am worried that my learning ability can't keep up with the progress of the course. This problem has also been solved in Consumer Innovation, that is, they will have special customized course services according to the theoretical basis, learning time and learning ability of the students, which will be of great help to the improvement of learning progress and grades. I think my heart and conscience are very good.
