WorldPol and Geopol.
Worldpol has Gil. People are going to tell you that the class is boring and blah blah. But! He is a good teacher/lecturer. His no BS attitude provides a good learning environment. This subject is fundamental for IR imo. I'm not quite sure what they teach in 1104 but I'm sure there is some cross-over in terms of content.
Geopol has John for S2 and a new lecturer for S1. John mumbles A LOT. Now this is not to say that the subject is bad. The subject is broad enough to give you a really good feel of IR. The subject takes a multi-dimensional approach towards teaching as it shows you all the influential factors of an event. In addition to this, its pretty fun cause you get to learn a bit of everything ranging from environmental politics to space politics. First couple of lectures will be boring as it goes over some historical stuff though.
