In Data Science Specialization, I see two optional video contents -
Live recordings with Hadoop Jan 28, 2018
Live recordings with Spark Scala Jan 28, 2018
Do these videos cover something extra which is not covered in the non-optional sections of the course?
Please reply.
No, these are the live session recordings. These videos also include live discussions and Q/As with learners. So, If you are not so clear about some concepts you might find these videos helpful.
In past, a number of users found these very useful in their interview because of the Q/As.
Thank you for the response.
It would be helpful for all students if the important Q/A can be incorporated as an additional reading or chapter contents. These video recordings are very long and if only Q/A is extra, then it can be incorporated separately.
That would reduce the course duration and help all students in finishing the course quicker.
Thank you good suggestion. We will plan to work on this.
