Go to a community college for a few years and then transfer to a University after you reach the maximum transferable credit limits. You’ll save about 50% on tuition depending on your state
Make sure the college you plan to transfer to will actually accept your credits. Do this by going to that college with a list of the community college courses, and asking which will be transferred.
If you don’t do this, half or more of your community college credits may not be accepted.
