Really interesting course. The interactive coding sessions with swirl are especially useful. Would be great, if you provided sample solutions for the programming assignments, in particular for week 4.

"R Programming" forces you to dive in deep.

These skills serve as a strong basis for the rest of the data science specialization.

Material is in depth, but presented clearly. Highly recommended!

Disjointed and not cohesive. Start with the basics and build from there. The assignments are a waste of time.

Theory and online lectures are fine, assignments are not (at all) consistent with the level in the lectures.

There is a huge gap between what they teach us and what the assignments ask. Had to get a lot of extra help.

It would be really helpful if the teacher gives more examples or graphs when he explains some concepts.

It's totally difficult for me. Some of the assignments are really hard to work out for me as a novice.

I bit disappointed with the video lectures. I opted for external resources instead.

There's a big gap between the content in the videos and the required assignments.

The assignment is way harder than what is actually taught in the video lectures.
