First, "institutions obey", when you are not accepted by various voluntary schools, do you agree to transfer to other vacant institutions?
The second is "professional obedience". When your file is transferred to a university, the reported major is not accepted. Do you agree to transfer to other vacant majors?
"University obedience" will only be effective if the school you apply for doesn't admit you. Generally speaking, this probability is relatively low, because ordinary colleges and universities will not admit students who have not filled in their volunteers.
"Professional obedience" means that you have passed the school's investment line but can't be admitted to your major. At the same time, there are still some majors in the school that can admit you, so you will be admitted if you obey the adjustment of your major, and you will drop out if you don't obey the adjustment.
Once the person who obeys the adjustment is admitted, all the volunteers behind will be invalid. Therefore, candidates should not only pay full attention to the column "to be adjusted", but also fill in the blanks carefully to make their statements specific and clear.
