Key Finding: Users scoring above 67% (Mastery) had a 97.5% pass rate (39/40 candidates). Scores below 63% represent a significantly higher risk.

Does Revision Work?

Predictive accuracy improves with practice

Your Mastery Score (r=0.835) is a statistically stronger predictor of your exam result than your First Pass (r=0.757).

Strongest Indicators

Which question types matter most?

Please note: "Diagnosis" type questions are the most predictive (r=0.759) as they constitute the bulk of the exam. Please note, correlation factors are naturally lower the more granular the data.

The Power of Practice

Our multiple regression analysis confirms that: Volume is an independent predictor of success.

Even when controlling for a candidate's baseline performance, there is a statistically significant link between the total number of questions attempted and ultimate success on exam day. Putting in the reps directly translates to results.

Impact: For every 100 additional questions answered, candidates saw their real exam scores increase by an independent average of +1.1%.
