Comprehensive education curriculum
Employment guidance course is a comprehensive education course. Its function is to help students better understand career planning and job market, and improve their competitiveness in employment.
Required courses need to be retaken.
If one of the compulsory courses fails unfortunately, you need to retake this course. However, as long as you study hard, I believe you can pass this course.
Elective courses do not affect learning.
If you are unfortunate enough to fail an elective course, as long as you have enough credits, the failure of this course will not have much impact on your studies. So don't worry too much.
Consult a class teacher or counselor.
If you still have questions about this, I suggest you consult your class teacher or counselor, who can give you more accurate answers. I believe the problem will be solved.
