COLLEGE PREP & SUBJECTS

Thirteen subject tracks aligned to introductory undergraduate coursework: derivatives and integrals; matrices and vectors; probability and inferential statistics; logic, sets, and proof technique; classical mechanics through quantum basics; reactions, bonding, equilibria; cell biology through ecosystems; sorting/searching/graph algorithms; stacks/queues/trees/heaps; logical analysis and critical thinking; micro and macro economics; grammar and rhetorical structure; and cognitive/social psychology.

Each track is built as a graduated quiz pack that introduces a topic, presents a worked example, and then quizzes increasing in difficulty. Wrong answers always reveal the explanation, not just the correct option. The pack is sized for self-directed study (~30-60 questions per track) and aimed at students preparing for a placement exam, brushing up before a course, or supplementing existing classwork.
