When Xi Jiao Tong University is admitted, it will be selected according to the principle of giving priority to scores and following the principle of voluntariness. Above the minimum admission score, candidates who can't meet the first major's volunteers will file according to their second major's volunteers, but still can't meet their third major's volunteers, and so on. When a candidate's professional volunteers can't be fully satisfied, the candidates who obey the professional adjustment will be randomly transferred to the professional category where the enrollment plan is not full, and the candidates who don't obey the professional adjustment will be dismissed according to the policy.
