Question 2: This question has been answered in the last question, so I won't repeat it here. As for the file transfer, if the final political review is passed, the unit you apply for will give you a file transfer letter, asking your original unit to help you transfer the file and send it to the unit you are about to report.
Question 3: Since I have graduated, it has nothing to do with the school. Since your student status file has been transferred out of the school, the political review will not go to your school.
Question 4: Our political examination began about one month after the physical examination, which varies from place to place in China, but the list of people who passed the physical examination is usually published about seven or eight days after the physical examination, and it is also published about half a month. After the announcement, you will be informed by phone of the materials for preparing the political review, and the relevant requirements will be notified by phone or online.
