Week one and two were not bad, one complaint I have with week one on two were the overwhelming amount of tools mentioned in the videos which are quizzed on. It feels more like being tested on memory. I don't think my memory is bad or anything, but I just feel like it is irrelevant, but I do understand why they're mentioned in the videos, it's just the quizzes. Other than that, week one and two were not bad.

As for week 3, wow. Week 3 was convoluted. Major problem I had with week three is that the videos are outdated. I do think Watson Studio is a great resource to use, especially if you want to work for IBM, but it was confusing to figuring out how to sign up for IBM cloud for free unless you looked at the forums beforehand. There should be a disclaimer or something to give learners a heads up to read the forums before doing anything; however I don't know if you can do that currently on Coursera, would not fault the staffs or moderators if it isn't possible to do on the platform. I've seen some learners stressed regarding to signing up and using IBM Cloud. Not only signing up on IBM Cloud was an issue, it was also the interface change that is confusing to navigate for me and others. Other than that I've got everything out of the way and managed to complete week 3 and this course without being stressed out over these problems.

Anyways, continuing on the next courses and acquire the goal to get the certificate despite the problems I had with this course.

The basic content was helpful, especially for a beginner. However, it is imperative that the videos be updated to match the current version of Watson. They now show a defunct DSX environment that is very different from the Watson environment being used. One of the videos that the course analytics labeled in a "helping" pop-up comment "Was the most visited and considered important by learners" was the confusing outdated one...no doubt this was the actual reason learners played it over and over trying to make sense of it, not because it was especially valuable for learning. Another suggestion: many of the videos or reading material used a lot of jargon and DS terms as if they assumed that learners already knew these terms. It would be helpful to have an online glossary for each course with short definitions of the terms that are thrown around casually in the early videos, and sometimes defined later in the course (or maybe will be in later courses in the certificate), but that many learners are not familiar with at this point.

The actual course content was fine, but the link they used for accessing the software rarely if ever worked. It continuously showed essential software required for the course as "coming soon". Literally hundreds of students were reporting this problem in the discussion forums, but the only instructor feedback was "clear your cache and try again". Which was a not only a solution that had no bearing on the server side cloud environment features, but in many instances made the situation worse.

My only feedback is to PLEASE PLEASE make sure the software environment is working, and to PLEASE take student comments that they cannot access the environment seriously and propose real solutions. In the event that the environment is simply not usable, please suggest other methods of working through the material- IE, how to install Jupyter and Zeppelin on our local workstations.
