the lab is hard to access

Not up to the expectation

exams are not challenging

Very confusing at times.

it will help in job

Labs can be better

More SQL needed.

very important

SQL is useful stuff, and the other courses in this track (data science professional certificate) are great, but this course has way, way too many errors in assignments, workbooks etc. The course material needs a major overhaul to make sure

1. Assignment problems are clearly and unambiguously defined

2. Example syntax actually works in the SQL dialect being used in the notebook

3. When saying stuff like "create table like in week 2 Lab 1, part II", make sure that part 2 of lab 1 in week 2 actually has anything to do with creating tables (it currently does not), etc.

4. When saying "replace the part in angled brackets below with...", make sure there actually is a part in angles brackets below

Etc. etc.;I have wasted a lot of frustrating time trying to figure out stuff that had nothing to do with SQL because of the sheer amount of errors and inaccuracies like this in this course.

Graded peer assignment links are not working. It seems no one actively maintains the course content. Never expected this from IBM

The beginning started simple enough to follow. The learning curve jumps from 0 to 100 in a short time. Not an ideal intro course. The labs are much more complex than what is taught. Instructions how to restart and operate a Run a new SQL was not shown and I had to spend lots of time trying to figure it out on my own. The powerpoints and information are easy to follow but the ease of use through IBM's platform is not friendly. Definitely easier places to learn as I have taken other courses online for intro SQL. I wouldn't recommend purchasing this. I'd either use it in a Free Trial or Audit it. For that value, you can spend your money elsewhere.

1. Lots of the slides have repetitive content, for Ex. different type of joins, Every slide have some repeating lines/audio. Could have taken some different use case or else could have combined it making it a single slide for each joins.

2. The "Table Loading Issue" its been a week now I am facing this issue, even have posted in the forum, the solution provided is also not working. Every time I try loading the table in db2 it fails, without giving any error/warning message. I am almost done except a few assignments and final peer graded assignment due to this I am not able to complete my course.

I did not find the course structure, contents, way of teaching at all good.

I spent more time figuring out how to upload data on IBM DB2 storage than practising. I feel in this course coursera must look into ways to make it more learnable, I seriously will say, I was unable to learn anything from this course I had to spend alot of time on google and other learning websites to figure out how to code in SQL.

In many assignments I just had to skip them because connecting to IBM is very stressful and difficult thats why I was mostly able not to connect with it.

Course just not particularly well designed. There are typos throughout, several of the instructions are outdated (DB2 interface has changed and course has not been updated to reflect the changes). Some of the answers to the problems do not work. Some questions are poorly worded and the solutions provided are not for exactly what was asked in the question. Course spends a large amount of time on relatively simple material and then quickly flies through more advanced material by giving one example but not actually explaining how the queries/functions work.

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.
