The main reason for my low rating is the following:

1. The endless issues with the db2 console - an absolute nightmare to work with if you are not in the USA. Horrible experience. This slowed my progress down significantly to the point where I no longer wanted to carry on with this course

2.Not enough practical examples - as a result when doing the assignment, you want to tear out your hair. By my estimate, the Assignment should take no more than an hour if you have worked through everything.

Nice content, but lot of struggles with the tools. Watson studio has updated/changed the layout since the course was created, the content and description of the tasks in many cases don't live up to the real life situation. That's very frustrating, and you can see lots of people experience it if you check the weekly discussion forum. If the tool worked better (and if it would be better descried, as for somebody who never worked in Watson studio before) it would have been 5 stars.

they need to make sure that if an honors course is offered and it's completed and passed, that that student gets a prompt honors' certificate as was clearly stated in the course, instead of that student trying to contact/get help from unhelpful staff (whose second language is english) that ignore your pointed questions, pass the buck and don't help you resolve your issues. the coursera staff needs to get it together because they're highly inadequate and it shows.

I don't think the peer graded assignment is reviewed objectively based on the rubrics. The reviewer did not leave any comments about my "wrong" answers. I can not find where I did wrong as I already included the required clause in the query statements and got the right results. This is somehow disappointing. Even though I passed the course, but I got a lower score than I expected. I did not get any information about my "wrong" answer.

Lab was down for the entire time and it was really difficult to talk to someone and resolve the problem on time. It took 2 weeks for me to finish the final assignment due to lab issue. It was just waste of time any money spent on subscription. Coursera team said its 3rd party issue and they cant really help. IBM team was not providing the required solution on time. I got help from fellow students from the Forum and from google.

Although the first three weeks of this course were very educational, my motivation dropped considerably due to the difficulties I experienced in the laboratories of the fourth and fifth weeks. Although there were no errors, I got errors again and again and I had to delete and recreate the things I had prepared for the database connection. It was the most tiring course I took under the IBM professional certificate.

So many of the labs contain out of date or broken code, or simply don't work. The course also doesn't explain things properly and requires learners to make massive leaps in understanding and logic with little support. I had to get a friend to help me even get the labs to run, and then explain the content to me.

The only good thing is that I now have a basic understanding of db2 SQL - hence the two stars.

Too complicated to debug about the IBM tools, Its took me a tone of time just wandering to check password and username and too many errors without any solutions. I quite all the course not because I could not understand the content or could not do the exercises or lab, just because of the IBM tool too annoying, complicated and the instructions are out of date, also not details.

I am so far into this program that I can't turn back but level of instruction is ridiculous .. I'm learning more from YouTube than from the actually course the incomplete instruction and explanations are frustrating. Add to it the CONSTANT system issues, they are a distraction and they waste precious time. There is no way this course doesn't require prior knowledge.

it would be more helpful if the resources provided actually worked when needed. Nothing is more frustrating than following the lab instructions and not being able to complete it because the downloaded data wont load into db2. Forget trying to get timely help. That doesn't seem to be a priority for the 'education'.

Not great -- mix of SQL and Python that doesn't do enough SQL. I learned a lot of Python just to make simple database connections and run SQL queries -- it doesn't do justice to Python and isn't very helpful to learn SQL that way. The course would be better with just more SQL, and probably not in IBM cloud services.

Instructions and Labs were outdated, and the course material didn't accurately reflect the current tools. Professor assistance was also poor, having to wait numerous days just for a simple response. Dealt with the most technical errors during this class. Also, ran into issues regarding loading the DB2 instance.

Very hard to complete. Using the IBM Db2 service has horrendous. Because of the constant errors in using this service, it was a very jagged learning experience. I spent more time trying to find help from the staff on how to stop receiving open console errors than actually learning.

Strange tasks with errors, long waiting time for review, very bad support in the forum.

When you do week 6 will not change anything, the acquired knowledge will not be marked anywhere. Support says there would be a yellow banner "with honors", but I still had it after week 5.

I like the course but instruments for it (such as IBM DB2) are unavailable. Instructions with troubleshooting steps provided on forum sections are not working. It's clearly a mass issue affecting a lot of students. And coursera is not providing a real solution for us.

the instructions weren't very clear and the assignments weren't challenging but they were really tedious. I stopped part way through the peer graded assignment simply because the questions annoyed me more than challenged me. IBM can do much better than this.

Some terrible explanations. Several videos of were 6+ minutes of someone just reading a list of PROPER NOUNS and Definitions with zero context or explanation. The last 5% of content and peer-graded assignments is far removed from the rest of the course.

Would have rated it much better IF the professors / instructors did more to update the labs and coursework, spent way too much time figured out errors and reading forums, when this all could have been avoided if the instructors were proactive

The course is very outdated. It shows you ways to make JOINS that have not been used in the industry for more than 40 years and only in the last chapter do they show you the current Joins.

It is also not possible to connect Jupyter with BD2.

Pretty terrible quality labs, barely explaining the material on connections or using SQL in python. No one can progress in the course because of some kind of error. It's been weeks according to the backlogs on the discussion forums.

Course content is good but giving 2 stars as sometime the jupyter notebook sql had issue connecting to the ibm Db2 database instance, Skills network lab doesnt work sometime and I had to do trial and error to submit the assignment

The sql is easy, but the course makes it complicated for no reason. Instructions are incomplete on assignments, and issues are known to teaching staff. Ends up wasting 3 hours of time trying to solve known course issues.

I found the course very dry. Parallel I was doinga python course on Udemy, the 100 day bootcamp, and the contrast with the energy you get from Angela in that course compared to this Coursera course was very stark.....

The course itself it's very well made, but the app used to exercise is really bad. Sometimes it barely works and it makes it very difficult to follow the requests of the exercises.

Excessive time spent on getting stuff to work. Very little added value beyond simple definitions. Peer reviewed assignments are a disaster - people can give points as they wish....
