该准备多少资金

我的offer里写的是：
In view of your excellent academic performance, we would like to offer you an Assistantship which will pay $xxxx for the first twelve months ($xxxx/month). This position also entitles you to a complete waiver of  nonresident tuition worth approximately $xxxx each semester.  You will be required to work 20 hours per week in teaching or research related duties.  This assistance will be continued beyond the first semester provided that your performance in both academics and employment is satisfactory.  You are required to maintain a GPA of 3.3 (out of 4.0) during the first semester and 3.6  each semester thereafter in order to maintain your financial aid.

You may be eligible for increased support in the future. The ECE faculty have several Research Assistantship (RA) positions that are often available to outstanding students. These positions are awarded based on the student's academic performance and research potential.                  

不是全奖，还差3000刀每年，问小米说是一般2年读完，但是i20上写的是36个月。我至少该准备钱签啊，家里美什么钱，所有存折加一起才25万。

大家帮我出出主意吧
谢谢先
