How to arrange the test sites of Shandong institutions' examinations, and do I have to go back to the place where I applied?
Not if you take the provincial exam. You can choose the nearest place, such as reporting to the unit in Zibo. But since I am in Jinan, I can choose to take the exam in Jinan, but I will go back to Zibo for an interview.
It seems that all districts and counties will also organize examinations for public institutions (usually after provincial examinations), and such examinations will go to the districts and counties where they are located.
