Amazing teacher! I have learned so much in this process that even my way to think data has changed a lot. Metadata is a new subject for me and through the course I get even more fascinated about data.

I appreciate the course has good content of information to learn and develop.

I would like to inform that, spreadsheet security & protection is not explained completely in this course. If these examples are added the course will be more helpful for beginners.

Thanks for the support to make process daily with this good information.

Great course for beginners and who are confused who to get started and what are the right things to think about while analyzing your data. This course takes a tour of querying data, ethics and security principles that an analyst should follow topped with many analytics community networking tips!

When I saw that one needs no experience at all to learn this, I was not convinced! However, with the detailed explanation, it seems that a novice can actually learn it. I've skipped much of the videos due to my work experiences but the videos are definitely detailed.

Bueno el curso pero se torna muy confuso con Kaggle. Sobre esta plataforma uno no llega a comprender que es lo que se quiere que se haga durante el curso con la plataforma ni para que, mucho menos entender el funcionamiento de la misma como se pretende que se haga.

The course on BigQuery was not very accurate. Even though the site is frequently updated. Following the instruction in the video and getting an error message can be confusing. You don't know if you're making the mistake or if the instructions are not accurate.

Its good but not excellent. This course needs a larger emphasis on SQL and less on spreadsheets. I'm not sure how prevalent Google Sheets are in the industry but I bet SQL is a more valuable skill.

I did like the soft sills part at the end. Bookmarked.

I​ want to give this 5 stars, but the instructions for BigQuery were out of date, so I was not able to complete some of the hands-on assignments. I was able to finish the course by completing the quizzes.

Overall very informative and touches on important aspects about data and the related issues. Would be nice to include more hands on practices with SQL or Spreadsheet in comprehensive and progressive way

This was a great course and it was in flow with the second course of the specialization. Gave good insights about bias, ethics, and protecting data. It also involved a lot of hands-on activities.

I liked that some assignments had me use SQL and get more comfortable using it. However I would have liked more assignments using SQL and Sheets to get more practice. Otherwise was pretty fun.

Too many obvious information for a person who has prior experience with data. Please cut the course short for those who already have grip over these concepts. Anyways, it is helpful and great.

This third Course represents a forest of learning: very good. Had trouble updating dates, because it made me miss the progress made on homework and knowledge tests in the first few weeks

Overall a great course, meaningful overview on theories about data preparation. It could have gotten 5 stars if it had more hands-on practical exercises on SQL included in the course.

SQL could've been better, Overall the course was really nice but SQL was difficult to setup(payment options*) and the activity of SQL should've been more diversified(commands).

The instructor could be more "connected" to the camera... it doesn't seem as connected to the student as some of the other instructors in this certification program.

There was a lot to learn and take in. The theoretical information was manageable but needed more time and experience with the tutorials, practices and challenges.

C​ourse is amazing . Only few things as Cert. sharing link doesnt work. also few datasets in Bigquery do not link or not work, have to explore more datasets.

I have only concern about the course is making the reading part brief and increase the video. Reading part sometime makes bore. Overall great course to take.

This course can be considered as step by step guide to one of the main process about the data analysis. Everything is well explained and in good progression.

It was insightful and high quality course. I've learned a lot about gathering reliable data. It would be perfect if course included more SQL exercises.

Big Query was a challenge, but SQL is one of those skills that requires lots of practice with different datasets to build your skill level over time.

This course was very informative. Introduced a lot of more challenging concepts that went well with the information garnered in the previous courses.

There were a couple topics that I wish the course had gone more depth in, or at the very least, directed me to resources so I could learn more.
