Learn the fastest safe path to the thing you care about.
Optimized mode is best when you want PhysicsGraph to decide the long-term learning order. Focus Mode is for the moments when you already have a destination: a test next week, a lesson coming up tomorrow, or a concept you want to understand today.
Example goal
Circular Motion
In this simplified example, Focus Mode can skip 27 of 41 lessons while still keeping all 14 lessons needed for the target path.
Why use Focus Mode?
Physics is cumulative, but cumulative does not mean linear. Focus Mode uses the Knowledge Graph to remove lessons that are not on the route to your goal, without removing the prerequisites that make that goal understandable.
Studying for a test
Pick the topics on your upcoming quiz or exam and spend your limited time on the ideas that actually feed into them.
Preparing students for a lesson
Teachers can aim a class at the prerequisite chain for an upcoming lab, unit, or lecture instead of assigning a whole chapter.
Following personal interest
Jump toward the concept you are curious about while PhysicsGraph keeps the required foundations in the path.
Skipped does not mean ignored forever.
Focus Mode narrows the immediate learning menu. If a lesson is unrelated to your goal, it can wait. If it is a prerequisite, it stays in the path. When you return to optimized mode, PhysicsGraph can keep building the broader course plan.
required lessons kept
lessons skipped for now
prerequisites preserved
The exact numbers depend on your goal and what you already know. The rule is stable: remove unrelated work, keep the dependency chain.
Three ways to select a goal
The Focus picker opens on the Knowledge Graph, so you can select goals visually and see the prerequisite path highlighted before committing.
Aim at one exact destination
Choose one target topic, such as projectile motion or torque. PhysicsGraph traces the prerequisite chain and prioritizes only what you need to reach it.
Prepare for a custom set of goals
Select several topics for a quiz, review packet, or personal study list. Shared prerequisites are learned once, not repeated separately for every target.
Focus on a unit without doing every lesson
Choose a unit and PhysicsGraph targets the unit endpoints. The path includes the internal prerequisites needed to reach those endpoints, while unrelated branches can stay out of the way.
Use Focus Mode when the destination matters.
You still get the safety of prerequisite-aware learning, but your daily work is pointed at the outcome you chose.
