Why you can trust the practice
Test prep is only as good as its questions. Every live item is put through a three-vote adversarial review by a strong model — hunting for a second defensible answer, a wrong key, or a claim the text doesn't support — and anything that fails is pulled from the pool. Scores are modeled on published concordance curves, not a naïve straight line.
