Greetings from Pittsburgh!
I generally recommend that you spend some time, at least at first, hitting the "view new content" button when you log in -- it gives a good overview of a lot of different topics.
Everyone here will be a happy enabler and help you spend any possible disposable income on pens, ink, paper, tools, wax seals.... (And trust me, as a student you probably won't have a lot of disposable income). You will have to learn for yourself what pens are comfortable for you to hold and write with. And that's going to depend on all sorts of preferences as well as what size your hand is. For example, I have smallish hands, so I don't want a pen that's too large and heavy to be comfortable for long writing sessions. I like to post (i.e., put the cap on the back of the pen when I'm writing) so I don't want something that's top-heavy and unbalanced when I do that. Some people don't like metal sections. Or hooded nibs, like on Parker 51s (but that just means more 51s for ME... ). Additionally, you'll have to figure out whether it's better for you to start out with inexpensive pens or save up for one really nice one that you're going to use as an everyday carry. And what width nib really floats your boat (I tend to like F and M nibs, but I'm starting to see the appeal of things like OB nibs and italic stubs). Or if you want vintage or modern (both have their plusses and minuses). And that's something we can't answer for you. So looking over a lot of different threads, and seeing a lot of different points of view, will help you maybe narrow down what you want. Although there is nothing quite like actually holding a pen to see if it works for you. You may, depending on where you are, have access to a brick and mortar store (I don't really, so I have to travel for that, and places like NYC and Boston are not exactly day trips for me, so those sorts of excursions tend to happen in conjunction with the holiday "visit the in-laws" plans). Or a local pen club where people can let you try their pens and inks -- I've gotten suckered into a bunch of inks and some pens that way, but at the same time I know that I'm probably never going to want some pens that other people rave about. And then there are pen shows -- which can be amazing places to find the grail pen of your dreams but can also be overwhelming (all those tables! All those PENS!).
