I​nstructor goes too fast on materials. Inconsistent code. Trouble with run some of them despite of copying them directly from resources

subquery examples were unnecessarily complex. ultimate course design and deliverables were up to the mark no doubt. more detail and easy to understand technical examples would be much appreciated.

Disjointed. Lack of continuity. Increased frequency of typos in video transcriptions/subtitles. Complex concepts not explored or explained sufficiently.

A​lthough the instructor is great, I felt like this course less about analysis and much more about learning SQL and spreasheet tools. They are very important, but they are still tools only. I expected to learn frameworks and tips about data analysis or more life examples on how to analyze data.

The instructor glossed over SQL too quickly, seemed like the lecture was for professionals. I spent the longest time completing this course.

This course is honestly very weak. It's very inconsistent. The volumes of the videos keep changing between high and low.

The instructor jumps from nested SQL queries to very basic function of SUM in spreadsheet in the next video.

Also, I don't understand why the course keeps jumping between spreadsheet and SQL. It would've been much better to cover one first completely before moving on to the next one. Changing the software continuously kills the momentum completely.

Gratitude!

I am in fact a lifelong learner and I had the opportunity to participated in many top notch development experiences. But none like this. I am amazed! 8:-)

Too bad I didn´t have an opportunity like this before. But never is too late.

I wish that many fellows come by and learn how to improved their skills. Thank you Coursera and Google!!!

Great primer for more complex SQL queries and data processing. I've often just leaned on post-processing data after doing my SQL queries in spreadsheets/python, but with these new tools it should make my processing much more front-loaded!

An excellent course for learning analysis techniques using Spreadsheets and SQL. Recommended for all engineering and data science students as well as for those managing businesses and human resource.

The course content is really good however the course challenge was a bit too easy. A bit tough questions would have made us more accustomed to the different tools we have learnt in this course

This course gives the limited knowledge about SQL. Some SQL query used in this course is advanced and the instructor write those query without providing enough explanation. And yes this course is great for introducing the process of data analysis but it is needed to take extra SQL course to grasp some of queries. Good part of this course is the instructor was great.

The instructor is clearly knowledgably and highly skilled. However, for people new to programming languages, there were many advanced concepts that were overwhelming. Additionally, some of the follow along SQL videos were much faster than they should have been and lacked explanation on a deeper level.

Very confusing course. The instructor explained everything too fast. Of all courses so far I have done of the Google Data Analytics Certificate, this is the only one I haven't enjoyed, and the one I was looking forward the most

Weeks 1 and 2 are pretty good, but then the rest just went from 0 to 100 in last then a second. Pace is way too high, specially in the SQL parts. On week 3, I left with a lot more questions than answers.

Needs more SQL practice of queries to be honest. Just having the students ram SQL examples and type them out.

I think this course was lacking a lot, I rushed through most of the topics, the labs were also confusing

This course was very confusing at times. It needs to be edited again, badly. As others have stated in their reviews, the difficulty of this course is significantly higher than that of the first four courses for the certification, but almost needlessly so. A lot of the difficulty stemmed from the fact that many of the SQL statements simply _do not_ work as written in BigQuery, despite the video showing them written and executed in BigQuery.

Concepts explained in the later parts of the course are used as part of numerous SQL statements in in the earlier parts of the course without any introduction or explanation. Many of the SQL statements are also used without any explanation at all. This is a great example of showing someone how to do something, but failing to explain why something works the way it does, or why a particular method is used over another option.

WOW. WAY too many questions were asked about ASC vs DESC. What an unremarkable topic to be so focused on, especially considering how easy it is to fix it if one uses the wrong sort order. Considering how many functions there are out there that are so useful, to focus on ASC vs DESC as much as this course did was so ridiculous. Focus on topics that don't take half a second to fix in the real world if you get them wrong. Holy cow.

Needed access to material like the glossary and some spreadsheets as they were locked. Things were not explained as clearly as they were in the other courses. Which made it difficult to take notes and pass the exams. Also had 2 Qwiklabs that wouldn't work properly. I couldn't download the worksheets to do the labs. Not impressed with this course

This is part 5 of the certificate program. Parts 1- 4 were very slow and boring, and took too much time to cover simple concepts in detail. It's now finally getting into more complex and technical concepts in SQL and spreadsheets, and it's going super quick! Now is the time to go slow and be thorough, and it's racing through the material and skipping steps in the explanations. It recommends links to lots of other free blogs and websites to 'learn more'. I've found these sites do a much better job at explaining these concepts, so what am I paying for with this course? Frankly, if it wasn't for the job placement assistance I would probably quit the certificate process at this point.

T​he course challenge was hard but I got an A. I have learned forum posts about the data analyst job market and alleged lack of entry-level jobs are being censored by mods. Enrolling in this specialization was a HUGE mistake for me. So I am going to finish up the minimum requirements, get my final paperwork and make these the last I ever take from Coursera or Google. This is my opinion, frank and honest, so it too will prob. get banned.

WORST INSTRUCTOR TILL NOW

Overall, this was the best one so far since it wasn't all review like some of the first ones were. That's on me because I come into this with some experience and the setup is so you don't have any. However, I can imagine if you don't have any SQL experience this could have been more challenging. There are some hands on activities, but not enough to really get the learner completely comfortable with new syntax and thought processes.

Course is easy to follow along, but to really get good at it you'll need to set time aside and go through the helpful links they provide you. I've bookmarked them all and grouped them by category (i.e. SQL, BigQuery, etc.). This way they'll be great references later on in your career.

Phenomenal course and course instructor! You have made the complex SQL queries quite easy to understand and follow through. Great job!

Notably, some of the video lessons had very low volumes.
