Affiliate Marketing Secrets

I am seventeen, I had to leave my school for personal reasons, I have planned on getting my GED when I turn eighteen, I plan on going to Northampton Community College directly after. I live in PA.
i have a few questions.
-Can I take the GED course before I turn 18
if so can I go straight into school I have completed?
-Should i be applying to school’s now even though the last year of high school i completed was my sophomore year?
This is supposed to be my senior year. a majority of my friends have already gotten their acceptance letters to schools and things like that.
-I want to be a photographer will any high end art schools take someone who only has a GED?
The Ged program i am interested in is affiliated with the community college I plan to go to.
if you can only answer one of my questions i dont care any information you can give me is greatly appricated.
Please do not leave links to web pages that do not have someone you can talk to. i dont do well unless my questions can be answered not just anyones questions.
Thank you for anything you can do.
