When I started with pre-requisites, I felt the exact same way. While every other subject was teaching me how the world worked, biology was just a bunch of terminology to remember.
I feel like its almost like your on an alien planet, and instead of diving into all the crazy technology and cool thingamabobs, you're sitting their learning the language and quite frankly... its boring.
Then, you have the language down, and you get into the molecular biology that truly governs how all living organisms actually work... and its freaking mind blowingly complex. Specifically, right after biochem you have an understanding of the basic organic chemistry that makes all of the reaction pathways in your body work, which you then combine with the ridiculous amount of different processes going on in the cell. Evolution takes what should be just a mixed bag of different molecules - an environment completely driven by probability, things like diffusion and reaction constants, where you would expect millions of side reactions and no productivity - and turns it into this beautifully well organized factory that is dynamically changing and reacting to its environment. Mind blowing, I don't know how else to put it.
I doubt much of that made sense. I wish I could explain it as elegantly as it deserves to be explained.
I HATED Bio my first two years. Then, BAM! I was considering a PhD (until realizing that I had more worthwhile things to do than pipette small amounts of fluid from one tube to another). Now, its to the point where things I used to care about... like hearing that Lady GAGA had manparts or that Jay Z dissed Lil Wayne on a new track... all just seem so bland and trivial in comparison. Biology, and in specific, how evolution has shaped and directed it, is fascinating. I think Code Blu said it earlier... STICK WITH IT. At least until you've had an upper-division professor who exposes to the logic of the cell and its processes.
With that said, let me beat some people to the punch:
cool story bro.
and of course...
