求救！关于伯克利PHD网申的问题！谢谢解答

网申系统里有如下一项：
List courses in progress and courses you expect to take before enrolling at ou
r school。然后分别列下Department  Course，Number  Course，Description，Units和 E
xpected Date of Completion几项。
其中， Units一项是什么意思啊？我该如何填写？

还有，有一个要国际学生填写的Preliminary Financial Information Form and Application for Graduate Fellowships，里面有一列项目如下：

Additional living expenses for the 2006-2007 academic year (nine months)
Note: Standard living expenses, which include food, housing, books, supplies, personal expenses, fees, and tuition, are used for determining financial need. If you feel you have unusual expenses or obligations that should be noted, indicate these in the "list other expenses" section below.

units應等同於credit，亦即該課程多少學分。

"additional living expense"的部分，我認為對我都不適用、或者無法估計，所以都填0。
