Fun, concise, and on point course walking new folks through (or a great review for not so new folks) the process of identification, basic change management, and reporting for dataset validation

I needed more time to complete the course than was allowed on the big quesry free trial. there should be a longer subscription that comes included with this course. I also dont need resume help so it would be nice if that section was optional

I felt that the course was not designed well for the sandbox, very often while following along I got errors like

DML queries are not allowed in the free tier. Set up a billing account to remove this restriction.

This was frustrataing.

Barley any material to work through. If I was completely new I'd barley learn a thing. The instructor is great but should provide more training excercises. ex Codecademy's coureses are so far VERY much superiour in their teachings.

I think the content is good but the flow of the course got scrambled. not sure how but. it seems the one is finished and the next is only partial but it seems the system does not want to move off this one.

Wasn't iterative. I don't know if it was the course instructor or what. I'll just have to supplement my learning with other resources.

Final test was unclear and half of the course is about finding a job in data analysis not about process data or anything related.

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.
