Good, but need more data/videos to solve the quiz

assignment submission process are quite complex

It is not entry course! Please be well prepared!

assignments where too hard for the given videos

说实话，上课内容不够实用，理论性知识太多，实践太少，而造成课上知识和作业的脱节，不适合新手学习

The contents are too basic and poorly explained

It could have much programming assignments...

theory and assignments from different planet

Extremely useful introduction to the basics.

Good, but you can make it more interactive!

Its good but found it a little theoretical.

This was a very necessary but boring class.

Programming assignments are way too tough.

Course Content could be more comprehensive

Old information and nothing motivational

Assignments were too hard for beginners.

Quite difficult for beginners but useful

I already wrote a review of this class

Instructor's video is not very helpful

Good Introductory course on R language

quiz and assignment level is advanced

Hope this to be more interactive :)

Very interesting course - Thank you.

It was a lot tougher than expected!

The assignments are too difficult!
