According to torrent sites, there are 5 days.
Day 1 = 7 lectures
Day 2 = 8 lectures
Day 3 = 8 lectures
Day 4 = 8 lectures
Day 5 = 6 lectures
I have heard people say there are supposed to be 8 hours of lectures for each day, which would mean that there is 1 lecture missing from Day 1, and 2 from Day 5.
So while there are 37 lectures available, I am assuming there are supposed to be 40. But I've never seen anyone with more than 37 lectures.
Please correct me if I'm wrong.
