If my high school GPA does not meet college requirements, is there anything I can do to change or add to it?
Enroll in classes at your local community college and get the best possible grades to demonstrate your ability to do college level work.
What is your GPA and classload? You might want to consider enrolling in a community college to finish your general education requirements to get a good GPA and then transfer to a 4 year institution.
I agree with the above. You need to show four year colleges that you can do college level course work. Enrolling at a CC for a couple of years and doing well will do that. If your GPA doesn’t meet minimum requirements, it’s really your only option. Stay away from for-profit colleges, the degree isn’t worth the paper it’s written on.
