You do not need a HS diploma to get into college, even an Ivy League one.
You can't do both; you can either get a GED or a regular High School Diploma.
You have to be 16 to get a GED.
I was 15 when I had to leave school.
I finally got my GED when I was 33.
I went to community college for a year, and after maintaining honor roll status, I received several transfer offers at really good Universities all over the country. I chose to finish my Associates degree at the community college, as it is cheaper. I am currently working on my Bachelors at a private University in my city. I am debating where I want to complete my Masters, either at University of Hawaii or Smith College(one of the Seven Sisters schools!)in Massachusetts. I may even transfer to one of those two next year to finish my Bachelors.
I have an Associates in Early Childhood Development. I am working on a Bachelors of Social Work/Human Development. I plan on attaining a Masters in Infant/Toddler Mental Health and working as a therapist as well.
To be a therapist in any field requires a Masters degree. Counselors only need a Bachelors.
I have Pells grants, financial aid, and scholarships.
Hope this helps and good luck!
