Will Florida State University accept the grade point average of a 2.5?
Not usually. If that is your high school grade point average very few four year colleges will accept you. You would do better to go to a community college. You might have the same text book in a college class as you did in High School. In a College Class, you would have to go through that entire text book in part of the semester, not a small part of the book in the semester. A better idea might be to try the military and learn some discipline. After that you will have much better study habits.
