Replay What You Missed
Strengthen builds a practice round from the concepts you missed on a study guide, so you fix the gaps instead of replaying what you know.
How it works
See what is tricky
Concepts you have missed show up on your guide.
Practice just those
Strengthen builds a round from the concepts that need work, in a fresh form when it has been a while.
Watch it stick
Right answers in a later session move a concept toward mastered.
Fix the gaps, not the whole guide
Strengthen counts as a study session, so a round keeps your streak going. A miss never takes mastery away from a concept you already have.
- ✓ Built from concepts you missed
- ✓ Fresh forms of old questions
- ✓ Counts as a study session
