The most plausible reason is that teacher speaks really fast.

Explanation: toa

Instructors need to adjust their speech and how they deliver it according to the level of knowledge and age of their audiences to avoid issues like students having problems to keep up with the class rythm. So, if the instructor speaks really fast, students may have problems to pay attention and take complete notes about the topics seen in class.
