How readiness scoring works

Every exam blueprint is broken into weighted sections that match the real test structure. When you practice, the system tracks your accuracy and coverage per section.

Your readiness score for each section is your coverage (how many concepts you have attempted) multiplied by your accuracy (how often you get them right). The overall readiness is the weighted average across all sections, using the real exam weights.

Set a study goal with a deadline and the adaptive engine will ramp up focus on your weakest sections as your exam approaches. Concepts you have already mastered get deprioritized so you spend time where it matters most.
