申请同一个学校不同的项目要提交多次推荐信嘛

RT. 最近在schedule推荐信相关的事宜，想问下申请一个学校的不同项目（这里只考虑Master），比如ucsd ece下的ce和cse下的cs，需要对每个项目提交三封推荐信吗？还是说在申请系统上只能提交一次？

Applicants may submit up to three applications for the same term with one application fee. However, each application must be submitted to a different department.

To begin a second application, complete, pay, and submit one application first.  Once the first application is submitted, return to the application website, login using the same login name and password, and click on the “Start a New Application” button. Please do not use the back button on your browser or start a new account to begin the second application. These actions will result in a second charge of the application fee.

看起来各个申请之间是独立的
