This course really started getting the student "Me" more accustome to using SQL in the BigQuery Database. I really enjoyed the ability to initiate queries on a 400GB dataset. Realizing the sheer size of that accomplishment that happens in a meer 15 sec is absolutely amazing. This is an incredible course.

I had a lot of challenges with this course but I would like to revisit the course material and do the practical areas again so that I get to understand the material. The lecturer explained the material in a very detailed way. I had challenges because it ws my first time doing data cleaning practically.

Great course! This was one of the best courses overall. The instructor, Sally, was incredibily good in her content delivery and mastery. Through this course, I got exposed to different Spreedsheet and SQL functions that will help me in analyzing small and big data. I have no regrets taking this course.

Absolutely amazing. I have learned so much - my head is spinning a little bit - which is a goog thing! Loved the hands on activities that really help to give invaluable practice. The instructor is fantastic! Loved the resume building/job hunting information at the end of the course. Highly recommend!

The instructor was great and encouraging. The lessons were concise and on point. I loved the practical sessions, they were well explained with enough assignments to practice. I can now follow the data-cleaning process with confidence and ease. Looking forward to learning more in the coming modules.

The information was very useful in every section. The logical problem solving skills explained by the host were incredibly deep yet simple, and let your brain wrap around the data over time. I think this is the best course I have done of these first four courses. Modules 1, 2 and 5 were standouts.

5 star for me because everything i learnt is new to me and got to learn about SQL and new EXCEL functions.

however, i only wish that the BigQuery access can be expanded without quota limitations for Coursera subscribers at least, if not for anyone

Recommend this to anyone new to data applications.

The course was / is excellent, except for few glitches where it is not updatad or synchronised with videos.

The Teacher Ms. sally Kim is an extra ordinary person, she knows her subject very well and so fluent that is simply great. I would love to see her again in any video(s). My salute to her.

Great hands on activities to ensure learners are able to practice whatever they are learning and not just following through.Also kudos on educating learners on various ways to customise their resumes to appeal to recruiters and be able to secure job interviews and even employment opportunities.

I was extemely intrigued from the start of the course as the course instructor was such an amazingly enthusiatic and energetic person . She made the course fun and easy to understand and also was very articulate in her speech. Anyone with an interested mind would benifit greatly from the course.

A great instructor. The course dives deep into data cleaning, provides many useful functions and query statements to use to clean the data. Though, some of them were already familiar to me, it was great to refresh them and see in a new light how they can be used for the purpose of data cleaning.

It is very interesting course as it gives very informative and realistic information. It tells that why data cleaning is necessary, how we can clean the data in spreadsheet and sql. Brilliant course. Especially I liked the way of explaining the functions by using the real life example problem.

Hands-on activities are by far the most amazing feature of this course. If I divide all the knowledge and skill, I gained from this course then 50% of them came from the Hands-on Activities. Thanks, Coursea and Google for making this amazing course series. Love and respect for both of you.

This course will help you the whole process of cleaning dirty data and making the dataset ready for analysis. The cleaning process is the most important process before diving into data analysis. And this course will teach you every aspect of data cleaning process using spreadsheet, SQL.

I learned a lot during the course, the teacher explained the course in a pleasant way, I am happy with my achievements, I highly recommended this course.

It was an intensive course, it was developed with examples, this allowed me to deepen the knowledge in Data Prepare in a pleasant way.

I really appreciate the instructor(Ms./Mrs. Sally) the best instructor till now in the course, she really made it fun and easy to learn trying to be interactive as well. Really liked her way of explaining and being warmly and funny at the same time.

Thankyou Ms./Mrs. Sally, Great work!!!

This was a very informative and thorough course. I like how encouraging it was, because the subject matter can be difficult when you're learning SQL and other programs. I feel like it was explained well, and I know what my employers are looking for when I begin my search for my career.

Sally Kim was, by far, the best instructor so far. Full of energy and knowledge. I appreciated her lecture style and presentation skills. Nice work! Great material in this course as well. Love working with SQL in BigQuery. This has whetted my appetite for more learning. Cheers!

Amazing, Got to learn a lot about how one structures a problem and looks at data, and different ways to clean Data in Excel and SQL using different aggregate functions. Do take up this course, if you are interested in Data Cleaning Process and the nuances that one has to understand.

The instructor in this course was great! This was the most enjoyable course in the program so far. Wanted to note: The Meer-Kitty PDFs in the coursse challenge are designed using a colour palette that isn't accessible. The colour combinations are painful and very difficult to read.

Having clean data will ultimately increase overall productivity and allow for the highest quality information in your decision-making. Benefits include: Removal of errors when multiple sources of data are at play. Fewer errors make for happier clients and less-frustrated employees.

The course was very interesting and simple to understand. I loved the instructor-Sally . She made all the concepts so easy to understand and remember. The pace and the level at which she taught was perfect for a beginner like me. She made the whole course so much fun to complete!

On this course I learned a lot about how to clean your data so it'll be more credible and have integrity on it. I learned also about the tools use in cleaning process like SQL & Spreadsheets. Lastly, I've got some ideas on how to build a resume that will impress your employers.

I loved this course, it was informative and helpful. I appreciated all of the knowledge it gave me, especially in resume writing where I've been feeling a bit lost. It was an addition that might not be necessary to add to a course but goes a long way in helping people succeed.

Sally is an AWESOME instructor!!!!! - The best module I've had thus far, very engaging, hands on with real datasets. I knew nothing about SQL, Databases such as BigQuery but after this course, wow , Sally explained so well that I even want to learn more! - Well done Google!
