Almost Panic Attack

So after Dr. Trefry brought it to my attention that I need to choose my even more specific major...
I checked what classes I have to take next year and it just lists "Environmental Geology, Physics I, Physics I lab, Civilization I (plan on sneaking around that one), and CONCENTRATION COURSES"
So I need to take 3-7 credits of these so called "concentration courses," which I did some further research on and apparently between Biological Oceanography, Physical Oceanography, Marine Environmental Science, Coastal Zone Management, and Chemical Oceanography there are QUITE the different concentration courses. So I can either take Calc 3, Invertebrate Zoology, Organic Chemistry, Intro to Aquaculture, or Hydromechanics and Wave Theory.
I don't understand.

Dear Advisor,

These are the classes I would like to take:
-Modern Physics(PHY2003)
-Optics (PHY5020)
-Weather Briefing (MET1999)
-Marine Zooplankton(OCN5103)
-Marine Meteorology(OCN5407)
-Ship Design (OCE 4573)
-Calculus III (MTH2001)

Please make it work.
love,
whitney!

It's just too bad that Dr. Windsor doesn't read my blog, and when I actually go in to talk to him I will probably come out of the office signed up for Basic Economics and Civ I.
