昨天的 DB2 考试使众多尚未来得急好好复习的考友败下阵来,It's really
a pity, hehe, not because we can't get the certification, but feel
sorry for the money used to take the exam. xixi
但是经过昨天十来个人的探路之后,对考题及所考重点和方向都有所了解
试后大家集思广议得出以下考试之要点, 望能对以后考试的朋友有所帮助.
就像 AIX 初次在工大考时, 过的人也是屈指可数, 但随着广大同学的前仆
后继, 考AIX已成为小事一桩. 我相信在来年的 DB2 认证考试时, 会有越
来越多的人通过,到时你也可以大声的说: 过 DB2 认证不过是小菜一碟.
不过别忘了今天花100元钱给你们栽树的师兄们!
May we succeed!
