How much do I need before I can start dynamics?

G'day guys,
I am a second year mechanical engineering student and badly struggled with dynamics this semestre. I will need to know my stuff better but to be honest, I was never taught the basics. To the point, I intend to teach myself over two weeks whatever I need to know so I'm at level with my class. The topics they learnt included particle dynamics with cartesian coordinates, normal and tangential coordinates and polar coordinates; all of which I know nothing about.

Could someone help me by telling me the topics I should look into to catch up to this point? An organised list of what things I should learn first would be very much appreciated.

Cheers,

V
