Though I do agree with you to a certain extent, you do not need to be rich to get a good score. As @“aunt bea” pointed out, many students that are URM or poor do get high test scores. There are a lot of ways to prep yourself for the SAT - I have had a vocabulary app on my phone since 7th grade and I just practice and learn whenever I’m bored and, really, that improves your SAT score literally by just clicking on some things and using your brain. Also, the app is free. Practice tests are also free, and your school/local library probably has some prep books that you can borrow (for free). Khan Academy also provides (free) videos for the new SAT. Studying for the SAT can literally be doing your homework or reviewing notes (not implying that you don’t do this, of course, but it is another way). Books are everywhere and reading any type of book will help you prepare.
You are right about the SAT score being an “intelligence test” of some sorts, but, and I honestly don’t mean for this to come out rude: colleges don’t care what you think. The system might be a little jacked to you but, really, you need to sell yourself to admissions and even if they appreciate a quality student like you, they have a caliber for their school and if you do not meet it they cannot care less. Colleges will admit the best students in their admissions pool and that SAT score might mean a whole lot if you transcript does not look competitive in any other aspect.
I think you should focus less on your EC’s and more on the SAT. Volunteer hours don’t actually do anything unless it’s for a club or scholarship. It’s better to invest your time in something else, like using (free) resources to study for the SAT. If your homework load is so heavy, then why didn’t you drop a class? 45 minutes on homework for an AP class that does nothing for you can be spent in some other productive way. Junior and senior year are the most important times in your high school life academically. There is supposed to be a balance between all aspects of your life in high school - social life, EC’s, grades, homework, test scores - and, at the moment, you seemingly don’t have it. Low SAT, high GPA, lots of EC.
Colleges obviously consider other factors but test scores are looked at critically and it is imperative to have a decent SAT score. I don’t think you need to start a thread to know that colleges look at more than your SAT score.
You have expressed concern for SAT prep being expensive, so I have listed some (free) sources that might aid you:
