I also had problem to focus on lecture because of way of speaking. :(
Explanation is sufficiently clear, but I get a little distracted by the way this professor speaks. Also, some of the quiz questions were not formulated very clear. Overall, still worth viewing the videos, it was very good to revisit these topics.
Good job teaching. Good summary and emphasis on how to keep diseases apart.
The subject matter could be better delivered! A lot of unnecessary verbiage leading to presentation that often do not assist learner
