Class Registration

I'm in the process of registering for classes at Masaryk, which was supposed to be done a month ago (yes, I have a procrastination problem...I'll get around to overcoming that sometime).  I've had several problems/issues with it.  First of all, the classes that are part of the actual program don't interest me and don't really advance my studies; they include Music in Czech Lands and Czech Film.  So, I am looking at the classes offered in English.  Most of these classes are master's level courses (it's a 3 year bachelor program, so 400 level is first year MA classes).  I have been working on getting professors' permission to take the courses.  The courses average an hour and 40 minutes a week, and will transfer back as 6 or 7 ISU credits.  So, there is the question of what number of classes to take.  Do I treat these classes like a 6 credit class or like a class that meets for 1h40/week?  I can't really seem to get a straight answer from anyone, so I'm confused.  One of the professors gave me maybe the best advice:  Just register when I get there.  

The courses I'm looking at include Remodeling Political Culture in Central Europe after 1989, the History of the American Presidential Elections, International/Transnational Orgs. and Euro Politics, The Making of Europe (Euro System of States since 1648), EU in European Politics since 1989, and Political Issues and Social Policy in the EU.  The last one is dual listed as the same class, taught by the same person, but as a 100 level class and as a 400 level class (but the same class and same meeting time, so of course I'm confused.)  Oh, I'll be taking a Czech for Foreigners class, which will help me communicate with people in the CR and with some of the elderly folks in Traer/Clutier, which I'm looking forward to.  Hopefully, I'll get all registered and get everything taken care of soon.
