就是每年能够成功递送材料的数量。

一般是学校收到的完整申请材料的数量， 如果维立克是申请必须的条件， 这个数目会略小于通过维立克面试的数目。

申请数是指学校收到的正式的递送资料，寄宿制学校通常有四种申请方式：
1. Complete the application forms which the school has on its website.
2. Complete the common application which you can find on the SSAT website.
3. Complete the common application which you can find on the TABS website.
4. Complete the paper application forms which you have either downloaded or received from the school.
无论哪种方式学校收到确认了，就算是一个申请数。

可以这么理解，不过一般招生官问的意义在于看你有多大可能来我们学校，建议不要回答太多所。
