Digital SAT

Knowing what you got wrong is the easy part.

Forge watches how you work the test (where you rush, misread, or second-guess) and turns it into what to change on the next question. The diagnosis and the fix, not just another score.

Built on the method of an instructor whose students break 700 on Reading & Writing four times out of five, most clearing 1500+ overall.

FORGE
What the map measures

Five dimensions, one read.

Every question gets read across five moves of thinking. Together they spell the name, and they pinpoint where your points actually leak.

F

Frame

Reading the question for what it actually asks.

O

Observe

Catching the details that matter in a passage or problem.

R

Reason

Working through an inference one honest step at a time.

G

Gather

Pulling information together across two places or sources.

E

Execute

Carrying out your approach cleanly, without slips.

What you actually get

It doesn't just score you. It tells you how you test.

After the diagnostic, Forge hands back observations like these, specific to how you (not the average student) move through the test.

You read accurately, but lose the forest for a tree. On "main purpose" questions you lock onto a vivid detail instead of the author's overall move. Your misses cluster where the right answer is the least flashy option.Read fine. Miss forest for tree. Flashy answer on main-purpose questions: trap. Boring answer usually right.
Observe
You answer the question you expected, not the one on screen. Add a constraint like EXCEPT or primarily and your accuracy roughly halves. The content isn't harder; the framing changed.Answer question you expected, not question asked. EXCEPT and primarily cut accuracy in half. Reread the ask.
Frame
You're sharpest in the first eight questions, then you speed up and slip. But your second-look changes are right four times out of five, so the instinct to slow down is correct.Start sharp. Speed up. Slip. Second look right four of five times. Slow down.

Practice that compounds

The longer you practice, the better it knows you.

The profile isn't fixed. You practice; Forge refines it. Within a few weeks it steers practice toward the dimensions you actually need, not the generic weak-spot list everyone gets. That longitudinal record is the moat: it can't be cloned, because it's you. Time to results varies.

Know where you stand

See your score. Then watch it climb.

Every student wants the number. Forge gives you one on day one from your diagnostic, then keeps it honest. Log every real SAT, upload your Bluebook and paper practice tests, and your whole trajectory lines up against your goal.

  • Log every score

    Real SATs, school PSATs, Bluebook attempts: one timeline, measured against the target you set.
  • Upload a practice test

    Snap a photo or PDF of any provider's score report. Forge reads it, sorts each skill into your five dimensions, and folds it into your read. It keeps the signal, never the questions.
  • Scored the way the exam is

    Your diagnostic uses Rasch / IRT scaling, the psychometric family behind standardized tests, so it reflects your ability, not which form you drew. A full-length, adaptive practice test on this scale is built in, for when you’ve done the work to make the number mean something.

About the scores. Forge scores are statistical estimates from your responses, to help you track progress. They are not official scores and do not predict or guarantee any result on test day. When you upload a practice test, Forge extracts only your per-skill performance and maps it to your dimensions; the file is processed and not stored, and the questions and passages are never retained. SAT® is a trademark of the College Board and Bluebook™ is its product; the College Board is not affiliated with, and does not endorse, Forge or Vindica Inc.

Questions

Asked and answered.

Most "AI for the SAT" is a chatbot with a system prompt: it explains the question in front of you and forgets you the second you close the tab. Forge doesn't explain the test. It watches how you work while you take it, and turns that into a profile of how you actually think. Anyone can clone a wrapper in a weekend; nobody can clone a year of your own habits. And it won't tell you you're doing great when you're not.

A quick Google or email sign-in, yes, so your profile saves and builds from the first question. Everything is free while Forge is in early access — no card, nothing to unlock. Want a look before you sign in? The score-report reader needs no account.

It's yours. Deletable and user-controlled: one click, no support ticket. Privacy is built into how the product works.

Your profile updates after every session. Score gains vary by student, and we don't promise numbers we can't keep.
