Each school has their own definition of a full time student, and the IRS goes by what the school says. So only the school where you are enrolled can clarify that status for you.
If you'll look on your 1098-T (if you received one) there's a checkbox in box 8 for "check if at least half-time student" Some colleges will check that box because if you're a full time student, then you are "at least" a half time student. Others will not check that box. But not checking it doesn't mean you're not full time.
Generally if you are working a full time job, it's extremely difficult, though not impossible to be a full time student too. So that's why you need to get clarification with your school.
