Second week of classes, and I am already starting to feel busy

Me being who I am, which is at times overly ambitious, I have signed up for 5 classes at the University of Otago.Now that I have finished one week of classes I can freely comment upon them.

1. GEOL 344- Advanced Field Studies, came here early to take this class, it gets done halfway through the semester!
2. SURV 208- GIS or Geographic Information Systems, this class will (hopefully) be very useful when I do a senior thesis, also GIS is very good for the job market. 
3. GEOG 289- Geomorphology, the study of landforms and their development, so far not a bad class, except their was that 2,500 word lab report for the first week, that was not so much fun. But I just went to the beach for a lab so that is definitely a plus! 
4. ENVI 311- Understanding contemporary Environmental Issues, this class is somewhat similar to a class I had with Joe Nevins, but it is a more from the New Zealand side of things, anyway I love the present lecturer and this is my fun class, because I deserve one of those every semester, right? 
5. GEOL 363- Hydrocarbon basins and basin development, so I am learning how oil is made! Also looking at a bunch of micro-fossils, not so hyped about that bit but it does have interesting portions, I will have more to say after lectures tomorrow (that's right, I have three hours of lecture and another 3 hours of lab for this class tomorrow, but at least I am done then, its a one-day class!). 

I either like these classes, or think that they will be very useful, so now I have the problem of trying to decide if and which class I should drop.  I guess I will see how the work load is and decide from that. Anyway, four at the end of the semester doesn't sound too bad.
