One process has a more level playing field, the other is clearly rigged in favor of rich well connected kids.
I'd prefer we provided the food, housing, education, and healthcare that would enable anyone to succeed on the SAT by eroding the worst disadvantages some kids face.
Practice twice a week leading up to the test with practice tests once every two weeks.
taking a prep course will help, but thats not necessary at all.
It's cold comfort to be told my parents fucked up. That's true, but it doesn't actually help.
I got in the elite range simply by buying SAT prep books. I memorized the vocabulary, and the book had enough tricks for me to do well.
Granted, I always excelled in math in school. I, however, did not excel in English (my 10th grade score was a well deserved C). But I still did great on the verbal section, and it was primarily due to reading 1-2 SAT prep books.
If you think you're going to start prepping 1-2 months before the test and do well, it won't work. For both the SAT and the GRE I started about 12 months prior (but very low intensity - a few minutes a day). I did even better in the GRE, scoring well in the top 1% nationally.
If you treat the SAT as a possible golden ticket for your future, you'll take it seriously and start prepping early. If it's merely a "Meh, that thing I need to do to get into a college", no amount of prep will help.
