我是23T2上的，曹老师教的，感觉还行这门课。不过说真的教的内容不多，写的代码也没有很深入的难度。
这门课需要python或java的基础，lab只做练习并不算入最终成绩。我建议lab一定要参加，因为lecture上不会带着你去写代码，只是简单讲解。
最后考试只有两题代码题和两题伪代码题，剩下的都是简答题或者计算题，难度适中。
The final exam is noly 4 hours to answer 6*2 = 12 questions.
Just notice you that you may do not have enough time to anwser all questions.
I got zero marks in the first assignment because Yifang Sun did not mention Spark is running on parallel. That means a code that seems correct on a single thread (which is the COMP9021 style), could have a different result on Spark. This lecturer is terrible and irresponsible I would like to say since a lot of the contents taught by him were wrong. Worse still, in the final exam, he asked students the issue in assignment 1 which led to almost 50 students got zero marks, though the associated answer had not been taught in the lecture at all!! Be careful of this lecturer!!
20T2
Lecter： Yifang Sun，今年是他第一年教书，明显感觉授课技巧不足，英文表达能力较弱。但也因为这个，他对知识点阐述是非常详细的，只不过几乎每周课程都会说错一点或者课件写错一点，两三句能讲明白的东西他要讲很多例子才能明白他的意思。
Lecture：上课方式是提前将录好的课程放在Google Drive和百度网盘上，让学生自己去下载观看。挺贴心的，对因为疫情在国内来不了的同学来说，避免了网络链接不方便的问题。课程内容，我个人挺喜欢的，因为有很多数学计算的部分我很喜欢
2Project+1Assignment+3Lab：lab不算分而且第一个lab是搭建环境，Project1的分数设置出现了大问题，只要代码没有run对结果就给0分，无步骤分，而且运行效率也影响评分。所以很多同学为了追求效率，不断完善修改自己的代码，修改到最后，之前对的地方给改错了，导致0分。第二个project和assignment明显就改进了，拆成了很多小步骤。
