申请University of Cincinnati ME 寄材料问题

我还没完成网申，看申请指导上说 “The additional materials to send to your academic program vary. At the end of your application, you will be shown what additional materials are required. You will also receive an email after applying that contains these requirements.”  
申请的同学,请说说需要寄什么材料，需不需要什么app ID.
我要申Mechanical Engineering
想先寄纸制材料，再完成网申。
谢谢先！  ：）
