Exempt from Federal Taxes....Will I still Recv a Refund for 07?

Ok, here is my predicament. I filed exempt on my tax forms like I do every year with 1 exemption thus preventing Federal Taxes from being taken out of my paychecks and ONLY Fica/Med/State taxes being taken out...I am currently a part-time student that works full-time and only 20 yrs old this would be the 1st time I could file taxes without someone else being able to claim me. My gross income for this year was 23,275 and I fall into the 15% tax bracket. Will I still get a refund for 07 or would I owe money?
