I hope the atmosphere or study could be better. It is extremely unsatisfying especially when I was struck by some questions and nobody helped. Meanwhile, I don't think Dr Winston is helpful because even I emailed him, he still didn't respond.

Explanations for formulas are not clearly laid out.

He's terrible at teaching. He is very unorganized, Doesn't explain what he's doing while hes doing it. I really wanted to do this course but it's so bad. I hope he redoes this course becuase it is terrible. Go to the drawing board learn from your many mistakes and make an interesting course worth doing.
