Course Difficulty

Medium

Time Commitment Required

2-3 hours per week of self study + course project (which required quite a lot of time)

Grading Policy and Statistics

No pre defined policy as such but the stats were poor.
From a batch of around 45 students, 2 students got AA with around 8-9 ABs and 9- 10 BBs. So with a decent amount of effort one could score AB and BB.

Attendance Policy

Zero attendance policy, but kept quizzes during class time. The quizzes were pre announced and attending the classes was not compulsory for giving the quiz. But honestly the professor was very good and attending live lectures was very useful.
