The best Digital SAT practice isn't more questions.
It's knowing why you miss the ones you miss. Most prep, free or paid, hands you a bigger pile of questions and assumes the problem is volume. Usually it isn't. Forge is an adaptive Digital SAT diagnostic that reads how you actually test, then points your practice at the real leak.
Most prep is built for a student who doesn't exist
Nearly every study plan assumes you're always on your best behavior, that you'll follow an immaculate three-month schedule without a bad week, a flagging week, or a new show dropping. That student isn't real. The real one has a life, an attention span, and a handful of habits that quietly cost points under pressure: rushing, misreading the question, second-guessing a right answer.
A bigger question bank doesn't meet that student. It just gives them more chances to repeat the same mistakes. Forge is built for how people actually test, not the idealized version, which is why it leads with diagnosis instead of volume.

When to use what (honestly)
Khan Academy
Genuinely great, and free, for closing content gaps: the grammar rule you never nailed, the math you forgot. Move on when you know the material but the score won't move; that's a behavioral problem Khan can't see.
An AI chatbot
Handy for getting unstuck on one problem at a time. But it agrees with whatever you're leaning toward, forgets you instantly, and can't see the pattern across a thousand questions. Fine for a hint, useless for a diagnosis.
A private tutor
The gold standard when they're good, and priced like it. A great tutor reads how you test and adjusts. Forge does the reading part for free, every day, and never has to leave for another appointment.
