Use multiple practice scores as a trend, investigate weak domains, and avoid treating an unofficial practice percentage as a guaranteed pass probability.
Use questions diagnostically
Record accuracy by domain and error type, not just the total question count. Wrong answers caused by knowledge gaps, misreading, timing, or guessing need different fixes.
Watch the trend across several sets
A single practice score is noisy. Compare multiple sets under similar conditions and look for repeated weak domains before changing the whole study plan.
Review explanations before chasing volume
A smaller number of carefully reviewed questions can be more useful than a large volume of repeated guessing. Update notes or flashcards from recurring errors.
