Unit Review Library

Every interactive review in one place. Pick a grade, a semester and a course, then the unit you're studying. Each review gives instant feedback, hints, step-by-step solutions, short lessons and a result with your Ontario achievement level.

Practise a little, often

Short, regular review beats one long cram the night before. Twenty minutes a day across a unit builds memory that lasts to the exam. Getting questions wrong in practice is useful: it shows you exactly what to fix while there's still time.

"The first principle is that you must not fool yourself, and you are the easiest person to fool."
Richard Feynman, physicist (Feynman, 1974)

Rereading notes can make you feel ready when you're not. Answering questions without looking shows you what you really know.

Start with Fast review to find your weak spots, or Flashcards for a quick memory check.
Use Practice on the topics that came up weak, and open "Need more info?" when you're stuck.
Finish with a Mock test, no hints, and aim for Level 3 or 4.
