As for me... I'm not from the USA, but this is my experience thus far.
I spent the equivalent of middle school in a 100% deaf school. When I entered high school, I went to a mainstreamed school that had support for deaf students, including interpreters in 50% of classes. (The number would have been higher, if not for the short supply of interpreters in the school.) I graduated high school at 16 (which is the standard age of graduation where I come from).
After that, for one year, I pursued the equivalent of an associate degree in a completely mainstreamed school with no form of support.
Later, I dropped out and returned to a different high school that likewise has no support for deaf students. I'm still there now, studying the equivalent of AP classes. Where I come from, regular high school classes and AP-equivalent classes are based in separate schools, and AP classes cannot be taken together with regular classes due to the wide divergence in their academic demands.
While I did explore the options of in-class interpreters and voice-to-text support, I ultimately decided not to use any of them.
I was raised non-oral to two hearing parents who both learned sign language with me, and actively encouraged me to use it. We experimented with speech therapy, but eventually decided to drop it. English is my first language, and ASL my second.
I can fully empathize with other posters who have voiced their frustration at being mainstreamed; I have had my share of bad experiences as well. To this day, I still kind of miss being in an all-deaf school.
But remember, every individual is different. We all walk different paths in life. But there's one thing I've learnt over the years. I'm now going to pass it on to you, from one deafie to another: If educational support is scarce, find other forms of emotional support from parents, counselors, whoever, that you know you need and will value. I find that such support goes a long, long way.
I wish you all the best
