I love how the course it's not limited to teach about the technical skills of a data analyst professional, but it also helps you discover some soft skills that make you a better human resource.

Absolute worst online class I have ever taken. I will be quitting this program thanks to this course. The video is outdated and does not match the tool you will need to use. Only written steps are added to attempt to explain the differences. No images or graphics to help demonstrate. And don't count on the discussion forum for help. Most of the answers will use the cop out that as a data analyst, you will be expected to adapt to differences in programs. In other words, you have to figure it out by yourself. Which ironically is the opposite of what they tell you in an earlier video, where they preach that you should ask questions and not waste time or effort doing unnecessary steps or trying to determine the best approach when you have coworkers and mentors to help explain things. I have used R Studio and Jupiter Notebook and Tableau. But the interface for BigQuery and the documentation in this course to help explain how to use it is useless and makes it impossible to get past week 3.

The lady that was doing the class was not a good presenter. She was difficult to pay attention to as she droned on and on. She was completely bias while trying to talk about not being bias. She was very condescending and unprofessional during the class. Google should better vet the presenters for knowledge and ability to present valuable information not just using what race, gender and identity. Unbiased presentation is unbiased data.

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 spent more than an hour on this. Whenever I type: 'bigquery....hire' I get in RED: Unexpected string literal "..."at [4:1]

So when I click RUN, I get nothing.

I am trying to attract your attention to the problem by putting a low score, the course is great otherwise.

Big Query sandbox videos and instructions DO NOT match the current interface. I can't even finish this course because of it. I'm absolutely frustrated, feels like a waste of all of the time I've spent in this program because I can't move forward now. I expected better from Google.

I appreciated the SQL usage, which I had forgotten, and BigQuery as a place to load db's instead of making a local one on my own computer. The rest was again too talky. The technical side of these courses is good.

the kaggle section is not aptly explained. also the BigQuery video section had problem with we as a course student not having that public data set in system, so could really not do practical task mentioned

Week 3 is so awful, that I am giving this course one star before even finishing it. You have students considering dropping the course because of the issues. It needs to be fixed immediately.

Support was very poor. I had an issue where the video and actual working on BigQuery wasn't matching up. The course took me longer than expected, and support was helpful at all :(

There is very little practical information contained in this course. I am extremely disappointed and don't feel this has helped me learn how to prepare data at all.
