Of course, failing professional elective courses is considered as failing, just like compulsory courses. I don't think any professional elective course is more important than the general elective course, and there is no so-called compulsory course. Elective, compulsory, professional elective, this can only be divided from the point of view of credits. You shouldn't divide yourself like this. Elective courses are chosen according to their hobbies or certain purposes, not dispensable, but dispensable. Elective courses also stipulate how many courses must be taken before graduation, right? Personal interests are different, so there are many elective courses. Of course, it doesn't mean that compulsory courses will definitely help you in your future work. There are many college courses, so it is impossible to learn them well. Come back when you know what you want. The above is purely personal!
