Eat at recruiting events...definitely helps the food budget.
Dont cheap out if you want to go on career treks...they might be the difference between landing a gig and not. So if you are serious about something spend the money if your school has a trek for it.
If you don't need a car dont bring or buy one...you can do zipcar (or whatever) and save a ton of money over parking, insurance, payment, and maintenance required of your own car.
Get a roommate if you can stomach the idea of it. Might work better second year after you know people better. Many of my friends with roommates have had great experiences.
Live in student housing...usually not as nice but usually saves you a bunch of money and often you wont have to pay rent during the summer internship or semester abroad.

However, I do not do profile reviews, don't offer predictions on chances and am far to busy to review essays, so save the energy of writing me a PM seeking help for these. If I don't respond to a PM that is not one of the previously mentioned trash can destined messages, please don't take it personally I get so many messages I have a hard to responding to most. The more interesting, compelling, or humorous you message the more likely I am to respond.
