The category of student does not change anything on your return. You can file with student as your occupation or not, it makes no difference. There are two areas you do need to watch out for: whether you are a dependent and whether your school considers you a full-time student.
With your income, you should not be considered a dependent as long as you have permanently moved out of your parent's house and it is not just a temporary absence due to going to school. If it is temporary, then you would still be considered their dependent unless you provided more than half your own support. The IRS has provided a worksheet to determine support.
Your school considers you a full-time student if Box 8 Check if at least half-time student is checked. This enables you to qualify for the American Opportunity Credit if you meet the other conditions.
