My worry is: as an early grad, many scholarships seem to be only available to those 17 years old and older. I will not turn 17 until May of next year.
Will this significantly impact my chances of receiving financial aid?
It can. If you are able to, stay in high school and get free college through them.
I would, but our dual enrollment program only allows a student to receive 18 university credits. I'll have 15 this year, and thus, it's of very little use to me to stay for one more 3 credit class.
