我帮你查了下，有两个IT课程，一个是一年半，一个是延长课程是两年的，看下面：
1 Master of Information Technology (Extended)
The course duration is two years of full-time, or four years of part-time study.

2 Master of Information Technology
The course duration is one-and-a-half-years of full-time, or three years of part-time study
所以你拿到得offer应该是超好种延长课程
