The best course in the whole series, BY FAR. Finally some lecturer with deep knowledge willing to share it, with not-so-easy examples. She is even too fast in some cases, especially when typing the database+table names while joining tables etc. This is how the course should look like consistently, instead of presentation tips, emailing etiquette and empty phrases about bias.

The worst of it was that the SQL questions on the Weekly Challenges and Practice Quizzes gave me the wrong results which led me to get the answer wrong multiple times! I even had a friend who is currently a Data Analyst and C++ Programmer look at it and she said that the function wasn't working and she got the answer wrong as well!

All in all, Ayranna was a great teacher!

I think that this was the first course where I learned something new about both SQL and excel. The program is very slow and up to this point I don't think that I have gotten much out of it. Still doing it though becuase I feel like the certification will be worth it. I think that there should be an accelorated course for those who are more advanced.

I thought this was the best course in the series so far. I would urge content creators to go over the tests to make sure they are accurate. The next thing I will look for are drills that I can do to practice joins, subqueries, calculations and working with temp tables. If that were part of this course of a separate course--that would be great.

The course material was good for a beginner like me but my rating aren't 5/5 is because the instructor was good but their way of teaching, personally seemed kind of bland or dull only comparing to the 4 courses already covered in this course. Otherwise the materials and teaching are good. If there was an option to give 4.5 stars I would.

The information is great, but sometimes, particularly with SQL the information goes too fast. It is true you can check the videos again but I think that in order to gain understanding we need to be given more excercises without a step by step guide and also slow down in some videos to study the structure of a query or complex matter.

The instructor has high speed teaching at sometimes,

and some instructions did not match the dataset or presentation

This course has 4 weeks progress, the beginning I can complete it in time, but not for the final session (Wk4) I think the content distribution between 4 weeks not balance so it is hard for me to plan my time to study

The lesson is great. The speaker is well-organized in developing the lessons.

It was a great way to learn about the analysis and answering the questions it entails.

The speaker had some accelerated explanations for certain concepts, but overall the explanations were clear. The analysis she is doing and how she is

This was the most challenging course within the Google Data Analytics Certification thus far! There are a few improvements that need to made to the content around ordering of the curriculum and updating to reflect changes in the sites they refer to. Hopefully, those will happen soon and this will be a full 5 stars!

Sometimes it is difficult to get BigQuery to work on my mac, I'm not sure if it's user error or operating system. It would be more helpful in learning sql if there was an interactive way to create query's within coursera. It would also be helpful to have a master document of what all the sql functions mean and do.

Now I know how to use Pivot table.

For Pivot table Chapter, I was confused when watch the 1st video. I know it's not easy to demo how to use the tools. I had to skip to Reading first, then back to video. Read cleared my confusion on what the video is talking about.

Some example of formulas are good to practice.

My take on this course, I enjoyed it.

My advise, if you a beginner beginner - please prepare to take longer on this course, because you will need to do extra practise possibly outside the course(search online). The lecturer is very knowledgeable, but a bit fast for a beginner. Please pace yourself.

Thank you.

Ayanna was great to learn from, I would give her ability to communicate a 5 star rating. She made it easy to understand and follow. I enjoyed SQL tutorials. My reason for a 4 star rating higher were the quiz questions. Sometimes the wording of the questions was off and did not match the videos or readings.

I very much enjoyed the course, I have got a lot of knowledge. Regretfully I could not follow some of the videos with my SQL because the data files assigned was not available at the time. I sent a message asking for support but I have not seen a response. A part from this I found the course very instructive.

Well, it seems that around my Saturdays or Sundays, when I use big query that the website gets glitchy and I cannot finish a project or two, it always come up they cannot find my file when i just used or uploaded it. Well maybe if I start making temporary file with WITH, there will be no more problems.

Analyzing part is very good, This is the most important part of the Data analysis phase and the instructions was very clear I just hoped they would give us more practical work to do and give insights on different Data Analysis such as healthcare, Business, etc.. for more knowledge in different domains.

The instructor is well experienced person so obvious

I faced a problem sql complex queries the instructor was so fast seems she forgot we are a begineer

As an advice read the reading part then watch the videos

i wish there was more exercises to write the queries rather than know the result only

This was the most frustrating course for me thus far. There were a lot of errors in big query when following along. This seemed more advanced and took me quite a few times to grasp some of the informatin. Although I've completed it I've made not to go back and review this course again.

This part of the data anaylytics course was the most challenging this far and I'm aware it's supposed to be. But the teacher moved bit fast in some parts and left me wondering where I should go or do, other than that I'd rate it a 5. Learned a lot of key skills I'll use in the future.

The course equipped me with the basic knowledge and skills needed in both spreadsheet and SQL such as the use of pivot tables, data validation, use of temporary tables, basic SQL syntax, and so on, to organise, clean, and summarize data to make sense for data-driven decision making.

It will be better to introduce more regarding SQL as it is a bit too fast. But of course I was introduced the concept which I can explore on my own. It a generally a good course which may explore everyone's concept of SQL and spreadsheet and how important they are in data analysis.

Analyse the data to answer the question: This course is very helpful and useful to obtain the results to prevent from bias.during this course i learned the advanced skills in spreadsheets,excel,SQL to analyse the results and show the variation from one to another by the results.

I saw too many mistakes in the last 5 to 6 topics, and Honestly, I had to slow down the speed of the video to understand. The tutor was going a bit too fast, the other 3 tutors were totally fine with the speed of teaching as I can understand them easier than her in this course.

I think some of the SQL and spreadsheet activity instructions and the videos should be updated. I had trouble following along occasionally, and sometimes the instructions just seemed to be wrong. A few times I had to use ChatGPT to help me figure out the correct query syntax.

Good course overall, but the audio was too low throughout. Also, some of the SQL content jumps right in without explaining enough. Thankfully I'm already familiar with SQL so it wasn't an issue for me, but I could see that being a problem for someone unfamiliar with SQL.
