Built for one student first

abbySAT was not built by an education company. It was built by one father, at a kitchen table, for one high-school junior — Abby, whose name is on it.

In July 2026 Abby sat a practice SAT and scored 1190. She wants 1500 by March. That gap is completely achievable, and the plan for closing it was not complicated: study most days, work on the things you keep getting wrong, and do it for months rather than for one panicked weekend.

The problem was never motivation. It was friction. The prep books and the accounts were all there, and they were not being opened, because every session started with a decision — which book, which chapter, which topic, how long — and that decision, made at eleven at night after homework, almost always resolved to "not tonight". Nobody skips studying because they have decided not to care. They skip because starting is a five-step process.

So the first version of abbySAT did exactly one thing: when you opened it, tonight's work was already picked. Three to five questions, chosen from what you had missed most recently, and an honest estimate of how long they would take. No catalogue. No planning. Nothing to choose.

Two things followed from that. The first was refusing to hand over answers. Getting a question wrong and immediately being shown the correct choice teaches almost nothing, so abbySAT asks for a second attempt and offers one hint at a time — and it records solving a question alone and solving it with help as two different results, because they are two different things.

The second was friends. Studying alone is what makes a plan collapse in week two: nobody notices when you skip. So abbySAT puts a small group of friends on one weekly board, ranked on questions each person answered correctly without any help. Not hours on screen, which anyone can fake. Your friends can see whether you showed up. They cannot see your answers, your mistakes or your target score.

Everything the app tells you is meant to survive being argued with. Your score only moves when a real, official result says it moved — abbySAT will never turn practice accuracy into an invented SAT score. Every question is original and labelled as such. The pace estimate shows its assumptions, and the projected range can go down as well as up.

It is public now because the parts that worked for one student are not specific to her. If you are a junior with a real target, a real test date and friends in the same position, this was built for exactly that.
