现在更换考点还来得及么？555 北京, 上海, received, comment, change

evaporated

想从上海换到北京，现在填写申请有可能通过么？

网站上说： We accept requests to change test center locations up until 75 days before exam day. Any requests received after that date will be considered on a case-by-case basis

ps：申请里的subject 填什么， change test center么？

      comment要不要多写几句原因, 这样通过的概率会大一些么？
