Content was amazing. Labs were really good. Videos from the lady talking the dense part need to improve. Audio from the lady had a messy stereo, also her pronunciation is not clear. Very bad quality

This course is amazing. The hands on labs was outstanding. But, the audio quality was poor. Needs to improve the audio quality. Overall a great experience learning Apache Spark.

The course content was pretty decent however, like others have said, the videos sometimes had poor audio quality and definitely could use a professional touch. The Week 9 Final Exam is poorly devised (i.e., multiple choice 20 question death march where you have to pick the query that is coded correctly....it's a lot harder than it sounds!) and definitely detracts from the overall learning experience.

Some assignment / lab questions were messy and/or worded incorrectly but it got the message through. Also, lectures had varying audio volume and quality based on the person talking. Would recommend polishing the questions/lecture audio a bit more. These were just some minor inconveniences. Overall great course with lots of mock real-world examples. Would give it a 4.5 if i could!

Good course overall

What can be improved:

1. Don't really like exam format - have to scroll screen and more test of memory than understanding due to time pressure. Passed anyway

2. There are some minor mistakes like wrong field names

3. Complex things like reduce functions can be explained better

Some textual errors and also Final exam question was asking for "YEAR" in one place but obviously had it mixed up with "DAY". Final exam not very clear multiple answers would sometimes be applicable but maybe those were "trick questions" and one should have gotten that

Course is really good, it was nice experience to work with Databricks platform. It has a good balance of theoretical and practical tasks. However quizes are quite simple, and final exam form is not quite good, and final exam tasks contain several critical mistakes.

Excelent to have a good understanding of how Spark and Data Bricks works.

Before start you should know SQL.

This is a hands-on course! I recommend!

Obs.: Databricks and Coursera teams should take a look in forum to solve some issues (bugs).

Good introduction to core topics. A bit confusing at times and could use some clean-up. But overall, I'm really glad I took the course and feel that I understand Spark SQL much better than before. Worth the time and effort.

very nice course, I am a working professional even though many concepts were new for me. Its awesome. But sound quality should be improved, sound just jump from left ear to right ear and then stable, its irritating.

The course experience would be improved by updated the material to match the current version of Databricks Community Ed., as well as some proof reading to correct typos, name mismatches, etc.

Course is good but lot of cleanup and errors need to be fixed. Final exam it self has incorrect questions. Also someone should be answering the questions raised by students in the forum.

A useful course for learning the basics of how to use Databricks for data analysis and a bit of data engineering. Worth the time for anyone looking to learn more advanced SQL skills.

Many of the videos (all that introduced the notebooks) were not necessary and I stopped watching them. The course introduced me to some spark sql functions that I was unaware of.

The material in the course is very good selected for learning Spark SQL. However, it might have been more neat prepared and the questions in quiz and exam could be more difficult

The content and hand-on coding is great. The sound recording need improving. It would be better if the coding part including more examples for one function.

Very good and useful course on the usage and power of Spark SQL, but only the final exam disappointed me in the sense it was pure SQL syntax oriented.
