The first three weeks were a complete bore. Very slow and only query writing was the fun part. Week 4 and 5 picked up the pace though. Saved the course.

Theres too much of query running and explanation in the videos and not enough content is covered.

If you have Oracle installed from previous classes, there is very little setup required. If not, give yourself ample time to install/configure it. Assignments take MUCH longer than the quoted 30 minutes.

Nice course, would be nice to have more exercises and more elaborated, but fair enough!

I am very disappointed in this specilization/course. I am working as a business analyst in a data warehouse consulting firm, so I was highly motivated to take all the courses! However, lecturer's poor delivery has taked me aback! It is really hard to grasp the information when it has simply been read to you! The lecturer is always reading and it makes me sick (sorry!). Anyway, I would not continue with the courses if nothing changed. In my opinion, if the lecturer respects students and his field of study, he does not READ from the script and lack motivation...
