Either you claim yourself or your parents do, never both.
Here are Tests To Be a Qualifying Child
The child must
be your son, daughter, stepchild, foster child, brother, sister, half
brother, half sister, stepbrother, stepsister, or a descendant of any of
them
- The child must be (a) under
age 19 at the end of the year and younger than you (or your spouse, if
filing jointly), (b) under age 24 at the end of the year, a student, and
younger than you (or your spouse, if filing jointly), or (c) any age if
permanently and totally disabled.
- The child must have lived
with you for more than half of the year.
- The child must not have
provided more than half of his or her own support for the year.
- The child must not be
filing a joint return for the year (unless that return is filed only to
get a refund of income tax withheld or estimated tax paid).
If the child meets
the rules to be a qualifying child of more than one person, only one person
can actually treat the child as a qualifying child. See Qualifying Child of More Than One Person to
find out which person is the person entitled to claim the child as a
qualifying child.
From what you describe it appears that you qualify to be your parents dependent. However, if you made more money then they did it may be more to the family's advantage for you to claim yourself.
Remember, the
Education Credits go with the Exemption, regardless of who pays. If they claim you, they get the Education Credits. If you claim yourself, you get the Education Credit.
Look at it both ways.
