Good starting point for understanding Big Data concepts - include some small exercises too in the course.

I would like to commend the great presentation. Even though it focuses on data sciences, it looks like it covers more on the traditional approaches. It would be great if it also covers some big data related area such as in-motion data; not static data sets. Thanks.

Navigation in the Final Exam/Info page needs improvements. when we are in information page there is no link option for Return to Exam home page except the link in the header.

In videos, the product version and size of the data studio and db2 are older version and small size, but when attending the question which depends on version is a problem, also newer versions are large in size. So incorrect information makes downloading problem.

I see that some of the images are not loading on these blog posts consistently. The videos on Saeed's post load consistently, though.

Is there something wrong with the images being hosted on www.bigdatauniversity.com?
