Three full courses, built to be used — not just read. Open a subject, drag the visuals to build intuition, lock it in with a quick check, then drill practice and short-answer questions with worked solutions.
Transformations, key features, exponentials, trigonometry, and discrete sequences.
Kinematics, motion graphs, forces, energy, waves, sound, electric circuits, and magnetism/electromagnetism.
Atomic structure, bonding, reactions, stoichiometry, solutions, gases, and atmospheric chemistry.
Functions, Physics, and Chemistry now include distilled printable notebook PDFs — plus teacher-style tips that show how to actually approach a problem, not just the final answer.
Drag the sliders and predict what the graph or model will do before it moves.
Answer a couple of questions per lesson and read the worked explanation.
Work the after-class set; track your score and review every answer.
Tackle the short-answer questions, then reveal the answer key to compare.
