The only hindrance I had is with understanding the problem statements in assignments. It would be better to use a more unambiguous text.
Emily Foxx's teaching methods in this course are the bomb. She does not give you code hints as Carlos Guestrin would, but rest assured she breaks the concepts down to basic learning blocks and does a pretty neat job at connecting the dots between blocks to present a holistic picture of the course.
I called out her name countless times trying to wade through the programming tasks. Guess that worked for me many times as I imagined her tutoring me in a PhD class and breathing down my neck to meet deadline on pay resit fees (akin to Coursera subscription charges).
Overall, 7-Star Course and Teaching Methods.
Great background through applications of linear regression and explanations that are step by step that allow the understanding and construction of learning.
