I'm glad I took this course. The instructor is warm, upbeat and very clear. The materials are very informative and helpful. I gained more understanding of cleaning data as well as built my SQL skills.

Probably one of the more technical courses of the program developing your technical skill set and actually preparing you to become a data analyst by introducing more hands-on Excel and SQL exercises.

I found the course to be both challenging and enjoyable, and I attribute much of that to our instructor. Their supportive and encouraging attitude kept me motivated to push through the difficult parts. I appreciated how they challenged us to think critically and pushed us to continue to develop our skills.

This course was great with explaining the process of cleaning data and I enjoyed the content; including the hands-on experience working with BigQuery sandbox. I chose not to sign up for a free trial, so I did not have the ability to update data in BigQuery, but was still able to follow along. I think I learned what was expected from this course and I enjoyed the instructor's pace. Thank you.

Pertaining to a quiz question "You decide to use a spreadsheet function to divide the text strings in Column G around the commas and put each fragment into a new, separate cell. You are using the SPLIT function."

The answer assumes your using google sheets, SPLIT is a function within the GSheet enviroment, however in excel its a tool, not a function so this True/False question can go either way.

Sally is one of the best instructors. Professional and also authentic style to engage students watching videos. For what was a lot of detailed information, her speech, intonation and hand gestures, combined with her personality made her credible and likable. So many people in videos are so monotoned, I find it hard to stay engaged. Great job also with encouraging students. Not fake “cheering on.”

So far, processing data from dirty to clean is the course that has taken me to experiencing what becoming a data analyst might be truly like by getting to learn, try out and practice functions in spreadsheets and SQL. I would highly recommend this course to those who, like me, knew very little about it and were somewhat afraid of trying. Plus, the course instructor is an absolute star. Thank you.

Great course with some excellent content as well. I enjoyed the practical examples more. All this helped with my overall undersatanding of the course material and te subject matter overall. With some more practice on the material presented and the applicable resources, I am sure that if I keep practicing I will be able to polish my skills in this world of data analytics which is rather new to me.

Another great course in data analyst series. Course content is great covering spreading sheets and SQL for cleaning data and making it ready for futher action. The best thing in this course was that a complete week was dedicated to resume building which might be boring for some but for many its great to have. I would higly recommend this course to all who want to become data analyst in future.

Although there were too much to learn in just one course and I had to keep in mind all of them, but the instructor was so good and talking so awsome that I could catch up with her and understand all the words. I did not need to replay the videos again and again like the last course that the instructor was so fast and talking in a way that I had to replay all the videos at least one more time!

This course is excellent in providing an overview of common spreadsheet functions used in data processing. It also takes a deeper look into cleaning and processing data with SQL using common statements and syntax. In just a few short weeks you can really start to gain traction as a data analyst. The course instructor is very knowledgeable and presents the information clearly! Great experience!

This course is amazing if you want to learn about data cleaning in general. You will learn a lot of pre-cleaning and cleaning techniques using spreadsheets and SQL , also you will know how to verify and report the integrity of your data. Additionally, it contains very good tips to improve the way your information is showing in your resume or build one if you do not have one. 100% recommended.

Really well designed course. Very valuable material especially the SQL part. Adding the resume & job search section was the cherry on top. It's very thoughtful of the course designers to include that section in this course, it has very useful information & it makes learners feel they have a better picture of what to expect & how to navigate after finishing this program. Very Well Done !

I love the instructor of this course. She spoke a good speed, clearly and with a lot of enthusiasm. She was always very energetic and happy in every video. I wish she will give more courses.

The course was simplified, interactive and fun. As a non data analyst looking into career change, I think I will really love a career in data cleaning. Sally did a fantastic job of making the entire course interesting, sharing the challenges that she faced when she started out served as an encouragement to me especially when I was having difficulty with SQL. Thanks Sally

Delivering lots of knowledge & bring it up to high level.

Need to improve SQL compiler download version instead of web site to get better & more practice.

Also spreadsheets should be more sample data to practice more.

I really enjoyed & have to give up to spend my personal time.

I could recommend this course to anyone and planning to translate English to Korean.

Great teacher! Make all step by step, keeping clean the way of learn during the couse. Focused in every formula and way of prossessing the data to make a better analyse after.

The way she put the part of resume during the cleaning process to show you how to lead with this step during your carrier was good, because she teachs how to lead with data on it.

This was excellent in helping me solidify some of the SQL syntax that I had already started learning while adding new functions. As someone who is transitioning (again) in my career, the end of this course built on my excitement for building a resume that will land me a new, and much better, job! The instruction throughout this course was fantastic!

I learned new things with this course and I found that data cleaning is one of the most important parts of data analysis process. It was an amazing journey, I learned about data integrity, using spreadsheets and SQL functions for data cleaning and how to prepare a resume in order to apply for jobs as a junior data analyst. Thank you Google!

This course does a great job at introducing the application of SQL and querying data in databases, cleaning it, updating it, removing unwanted entries etc. It also helped me learn cleaning data in spreadsheets, creating a database in BigQuery by uploading the data to query and how to convert it from one data type to another for analysis.

Great course and super interesting. One thing I would note is that the graded assessments mostly test concepts rather than skills. It would be nice to have a couple of questions that ask you to actually write a basic SQL query or clean a piece of sample data in the same way you get to do in the practice exercises. Otherwise, great job!

Fully packed with Data cleaning techniques, both in spreadsheets and SQL. The instructor was excellent and i loved how interactive the course was. I like the fact that i could get hands on activities to practice what i was learning. There were intances where i could follow the intructor with practice using links to templates issued.
