I don't know when all of this happened to you, but these days there's no excuse. I just googled for "how to increase my sat score" and the first result was this collegeboard.org page[1] called "How to Improve Your SAT Score." It referred me to the Khan Academy's free SAT practice course[2]. [1] https://blog.collegeboard.org/how-to-improve-your-sat-score [2] https://www.khanacademy.org/sat/confirmed
Let me reiterate: that requires for it occur to a student that you even can increase your SAT score. That remains non-obvious. After all, IQ tests aren't supposed to be something you can prepare for. So why should the SAT be, if it's this kind of supposedly holistic aptitude test? Why isn't "school overall" all the possible preparation you could do? Again, the difficulty isn't primarily in getting the extra resources…
If you are a high school student and the possibility of increasing your score doesn't even occur to you, I would suggest that college isn't for you.
