国外计算机博士全奖难拿吗？
PhD in CS is a very selective program. We are looking at 10%-20% acceptance rate for top schools， and even less among the best programs (ie stanford， mcs). The process can be broken down into these steps：
1. Interested parties will first need to find a professor who has an opening/is willing to supervise them on their project of choice. A good guide as to where to look is the CRA list of PhD programs(link is external ) . Once you have the mentor’s name it's just a matter of sending your CV and letter of intent to him/her.
2. After your research proposal has been approved you will be formally enrolled as a PhD candidate with the university. Usually， universities want to see some evidence of your programming skills so that they know you can handle the engineering aspects of the program. You should submit proof that you coded something (a website is acceptable）and get it reviewed by someone who knows CS well（professor， mentor， etc）. This step is important； otherwise， there's no point having you in the Phd program！
3. Next， you go through the usual application process with GRE， TOEFL， resume， LORs， SOP等申请材料。 The TOFEL 和 IELTS 的分数要求是总分不低于85分，各单项成绩不能低于20分。
GRE的分数一般要求是 Verbal不低于140， Quantitative不低于140，写作分数不重要（建议不要花太多时间准备作文，因为博士面试时，有的学校会单独给一篇题目让你写解答。） 每个学校对申请材料的数量和质量的要求不尽相同，所以需要大家自行到目标学校的网站上去查询。一般来说，材料齐全、格式正确、文字清晰、表达准确、重点突出，就能达到学校要求的标准了。
4. Then 在你所有的申请材料都准备完毕之后，你就可以开始等待学校的面试或笔试通知了。多数学校的计算机系会同时录取多位申请人，因此如果你收到了面试或者笔试的通知，说明你的申请材料得到了学校的认可。
5. 最后，在笔试和面试结束后，校方根据面试/笔试的情况和对你的考察，以及在你提交的申请材料中对你学业计划的评估来发放录取通知。
