Oh, Nejat. I was half asleep in his lecture doing the head-bob thing and he yelled in my ear to demonstrate resonance.
I was and am still TERRIBLE at physics... Nejat obviously knows what he's talking about but his grasp of English isn't the greatest so I often left the class confused as hell. Tutorials were the longest 3 hours of my week, and my TA's English was even worse.
I got a D and consider myself lucky.
