I graduated with a major in biology and a minor in chemistry. Now I am on my 3rd year of optometry school. (I learned about plants and physics in undergrad which has NOTHING to do with eyes.... weird how thats required.) I have just about 18 months left as well! Nearing the end finally!
Hey, just curious what you were a graduate student of, you mentioned physics so I assume a science major of some type. :) I did my bachelors in Biology, I'm in professional school right now--18 months left and counting! I think I finished up the hardest part though--I've only heard of one failing out past this point.
