Where is the college entrance examination for repeat students?

It's not whether you can, but that you must go back to your old school. Immigrants are not allowed in the college entrance examination, otherwise they will go to places with poor learning and occupy local admission places. It's up to you to repeat it. You used to take the college entrance examination there, but you have to go back to that school district to register. Some schools are registered in the school, while others are not registered in the local education bureau.
