I really enjoyed your graph theory course. When will that be finished ?

i am trying my best brother , working alone is a bit difficult.

Really nice!
Love your videos and your initiative.
What drives you to make these? According to my limited understanding, it would probably take a lot of time to make and even if you do earn from them, it wouldn’t be a lot :frowning:
Anyhow, great job and please keep it up!
