For the first part of the course, click below:
It took me a while to finish this part, mainly because the content seemed very vast and it required a lot of time to finish off a week in the course. As the course was self paced, all I had to do was sit down for about three hours in a week to finish it off. But after finishing the first two weeks of the course, the content became more easier and I was able to finish it off right away.
I intend to finish off Part Three of this course very soon as it would complete the course cycle from the Harvard X series.
