AI tutor, Sage
You'll never study alone.
Sage points you toward the topics and questions most likely to move your score, then stays with you while you work. Ask for a nudge when you're stuck. Ask for a full walk-through when you want one. Ask why your wrong answer felt right. Every response is grounded in explanations written by our tutors and reviewed by our mentor team, so the answer you get is the right one.
Context-aware hints on any practice question.
Step-by-step walk-throughs when you want the full chain.
Answer-choice diagnosis, why that wrong answer felt right.
YouI got this wrong. Why is (B) correct?
SageYou set up the system right, the trick is converting units. The question asks for kilometers per hour, but your answer is in meters per second. Multiply by 3.6 and (B) drops out.
YouShow me a similar problem.
SagePulling one from your weak-topic queue now, rate problems with unit conversion, medium difficulty.

Crafted. Tested. Verified.
How every question earns its place.
A question doesn't enter the bank because someone wrote it. It enters because four people agreed it reads like the real exam.
Drafted by senior tutors
Written by tutors who recently scored at the top of the digital SAT, working from the College Board's published domain specifications.
Reviewed by mentors
A subject-matter mentor, a PhD in math, English literature, or linguistics, checks every item for accuracy, voice, and difficulty.
Trialed with students
Items go to a small group of student volunteers first. Anything that lands strangely, too easy, too tricky, ambiguous wording, gets rewritten.
Calibrated against the real exam
Each item is re-scored against student outcomes on official tests. Only items that behave like real SAT questions stay in.
Most students don't fail the SAT because the math is hard. They fail because no one ever taught them to read a math problem out loud. That's a five-minute habit, and it's worth fifty points.
