Agree with most posters. AP classes and a good score (i.e. a 4) will enable you to get college credit for those subjects, which might allow you to graduate faster, or take more interesting/challenging electives.
Let’s get this straight right now: You are not getting a “free ride” in any case. Someone is investing in you. What you are looking for is investors. But you and your parents will be expected to share in that investment. Even at colleges offering tuition and housing, you and your parents will be expected to contribute some (such as for meals, since you won’t be eating at home). The awards are generally fixed when you start, but remember that tuition and housing costs generally go up as you progress. A condition of keeping the awards is good behavior (lay off the drinking and, for goodness sakes, don’t dare get caught with drugs near you) and a 3.0+ GPA, which isn’t easy in tough majors.
And here’s a major overlooked factor: There’s no guarantee that you’ll complete your degree in four years! I have found that especially true at Rutgers NB. There’s a variety of factors in that, but class availability is one.
How to get maximum investors: Finish in the Top 5% of your class. I know GPA and class rank is being downplayed, but it still matters when it comes to grants and scholarships. SATs are vital. Your goal is 2000+ (or 1400+ in math and critical reading. Writing is of lesser importance).
When it’s time, have your parents complete a FAFSA. That will help with needs-based aid. Sometimes, you might get awarded more than your actual expenses - but remember, it’s not your money, it’s someone else’s.
Talk to your guidance counselor and check-out online scholarship and grant opportunities. Keep plugging. And, when you succeed, give back to the folks who invested in you.
