Supplementary resources
This is the actual list — not an affiliate page, not a funnel. If something here is good, it is here because it worked.
Why this site is free
I come from a low-income background. When I started preparing for the SAT, paid courses and private tutors were never on the table — not as a principled choice, just as a fact. So I did what you do: I dug. I found the free material, worked out which of it was any good, and used that. Every single thing that got me my score was free and publicly available. It was just scattered, and nobody had put it in one place.
That is the only thing this site adds. I did not invent a method and I am not selling one. I found the resources, and now you do not have to spend the weeks I spent finding them.
Because none of it cost me anything, I do not think I have any right to profit from it — and I do not intend to, ever. No fees, no subscription, no "premium tier", no ads, no selling your data. If this site ever starts asking you for money, something has gone wrong and you should assume I am no longer the one running it.
The kid who cannot afford a tutor should not also be the kid with worse questions. That is the whole idea. Have fun, and go get your score.
Free, and worth your time
Ordered by how much difference each one actually made. Every one of these is free, and every one of these is where my own preparation actually came from.
A Telegram channel of more than thirty-five thousand people preparing for the same exam you are. This is where I found most of the free material I used — not one resource but the place the resources surface, along with people who will actually answer you.

The course behind my 790. It teaches the Math section from the ground up rather than drilling you on questions you do not yet understand, and it is complete — work through it end to end and there is no topic left that can surprise you.
For Desmos, in depth, plus the tricks that save you minutes you did not know you were losing. My whole Desmos foundation came from his videos — and then Ottocento filled in the conceptual gaps underneath it. Those two together are the entire Math story for me.
Half of what looks like algebra on this test is faster as a graph. He is the one who taught me which half.
If you are at the beginning and the basics are not solid yet, start here rather than throwing yourself at hard questions. It makes building the foundation feel like a game instead of a chore, which matters more than people admit when you have months of this ahead of you.
College Board's own app, and the only place you can sit a full-length adaptive practice test under real conditions — real timing, real interface, real scoring. Do these last, and treat every one as a live run.
College Board's own released questions with answer rationales, free, no account needed. Practise them on their site — their licence does not permit anyone, this site included, to republish them.
