Note regarding the lecture videos

These recordings of lectures are experimental at this point. The videos are uploaded next day after the class if they are recorded properly, otherwise they may not be posted.

Students attending the course at BSU may use these videos for review. However, it is highly recommended that students take notes in class instead of listening passively.
