是offer，不会变了吧！

问了一下系里的小米，隔了三天（周五写的）回信说4.5号告诉我最终结果
随后联系的老板也给我写了封信。（可能怕我着急）
Just to let you know that our department will give you the offer for PhD study starting at this fall. I suppose you will accept this offer and please prepare the qualify exam after you finish your master thesis this summer.
这封信是不是offer已经一定到手了。现在是不见offer不落泪啊。
