Brevlex writes every example sentence around your interests, then schedules it with spaced repetition so it sticks. No generic textbook line — a sentence for you.
Each source is a real, checkable word list that contains anonymous. We never claim an official exam-board list — none is published for the GRE, GMAT, or SAT.
