I want to go to film school, but have very little experience- help?

I have always been interested in movies, especially cinematography. I have wanted to look into film schools, but I have no clue where to even start. I am a high school senior with not the best ACT scores and not the best GPA (19 on my ACT and 2.8 GPA). I am taking colleges classes for my entire senior year, so by the time graduation comes around I will have an entire year of college done.
I am a strong writer, and I was a part of my schools news team. We should each come up with a script and film scenes for our schools news team, and my segment was “random facts”. I always had big visions, but it was tough making my visions come to life with not the best editing software and iPhone camera quality. I was also on my schools yearbook team for 3 years and I am familiar with interviewing and writing stories out of practically no information.
What I am worried about is having nothing for a possible portfolio. I also do not know which film schools I would qualify to get into. I know for certain that I will not get into the top film schools, but I want to find a way to get my foot into the door and start my life out of high school on the right track.
Any advice?

Film schools are pretty selective, and it’s getting a little late in the game! I know that some film schools request that you apply EA which has already passed.

My daughter’s an actor, so I have some knowledge of film schools but not of portfolio requirements. I do know that screenwriting is in film school, so perhaps writing samples could make up your portfolio. And maybe your random facts segments. My guess would be that they are looking for creativity and talent, not necessarily high production value.

Any school search has to start with budget though, and location if that is a factor for you. Have you started doing any college searches yet?
