SJSU,推荐信的问题

最近看到几处说SJSU就业好,我又很想去加州,就准备申个保底.但是今天看网站有点不明白

推荐信的要求,项目的页面上的说法如下,没太看懂...

Three (3) letters of recommendation are required. They should be addressed to Dr. Freund, and should be on the writer’s business letterhead stationery. Please use any of the following methods to send them:



1.       Sealed letters must arrive by US mail or express mail service such as UPS with the “Right of Access to Letter of Recommendation” form completed.  The form is available at:http://www.sjsu.edu/gape/docs/Recommendation_Release_Form.pdf .  Sealed letters arriving without the form cannot be opened or considered until a completed Right of Access form is received.

2.       Unsealed letters may be sent by you to Dr. Freund as pdf attachments to an email.   

3.       Unsealed letters may be attached to your vita and sent by you in US mail or express mail service to Dr. Freund.

4.       Pdf attachment letters may be sent by your recommenders to Dr. Freund by email.  However, they will be accepted ONLY IF the email is also copied to you by the letter writer in the same email.

1,3条都是纸推? 第二条和第四条没明白啥意思... 这个意思是要推荐人用邮箱给我转发?
