The info is well worth it whether you are a novice user or experienced, whether you are going into data analytics or not. The style of teaching and learning continues to be very impressive at Google!

The speaker of this course needs to explain what and why typing whatever is typing there. It is very confusing.

Module 5 and 6 are useless to us older (40 years of experience) people and we should be allowed to skip it.

Poorly organized. If you expect me to use coding, you need to actually have something written to go over, not talk about while showing on a video I have to pause, which takes forever to refer back to because of all the self-promoting drivel, and then expect me to remember it. And NO, I am not signing up for your program that I have to pay for after a certain time to use just learn what I need for the course. I'm already paying you. This entire program, not just this class, is needlessly drawn out. It could've been a single course.

The Google Data Analytics Professional Certificate is terrible. In the course, they just kept talking about I don't know what, going around in circles. Sometimes they liked to talk about things unrelated to the topic. They taught how to use tools very little, and they didn't even show how to use each tool. They just made us learn theories and sit there answering multiple-choice questions, which we don't actually use.

I faces many difficulties in the way of learning SQL. I think for learning SQL you must guided by a person physically at any time . Their are so many doubts are here, who will answer?

To be able to follow along further with the course you need to purchase access to big query. This is why there are such large drop-offs as the course continues on.

Why is this even a Coursera course? There's almost no hands-on component. This might as well just be a free series of videos on YouTube.

This course does not teach data analytics (how to add value with data analysis). It teaches tools used in data analytics.
