有没有学校不用交推荐信？

感觉让老板知道不大好

不过排名往后的学校也可以接受

不知道有没有这样的学校

You don't have to let your boss know.  In fact, a lot of people don't, until they know they'll be going away for school for sure.

Take a look at http://forum.chasedream.com/dispbbs.asp?boardID=13&ID=239846&page=1  It's got lots of useful information to help you get started.

Good luck!
