How is this calculated?
Predicted Score = Base + StudyBonus + PrepBonus + SleepEffect - DiffPenalty - RevisionDecay
Base = Past Average (weight: 40%)
StudyBonus = (StudyHours / AvgStudyHours - 1) × 15 (capped ±20)
PrepBonus = (PrepLevel - 5) × 3
SleepEffect = (SleepHours - 7) × 2.5 (negative if < 7)
DiffPenalty = (Difficulty - 5) × 2.5
RevisionDecay = DaysSinceRevision × 1.5 (capped at 15)
Confidence band = ±(11 - PrepLevel) percentage pointsFAQ
Frequently asked questions about exam predictions
How accurate is exam score prediction?
This predictor uses a weighted model based on study research and provides an estimated range, not an exact score. Accuracy depends on honest self-assessment. It captures key factors (preparation, sleep, difficulty) but cannot account for specific question topics or exam-day variables.
How many hours of study is enough for an exam?
As a general rule: 2–3 hours per exam unit/chapter for regular exams, 4–6 hours per unit for midterms, and 6–10 hours per unit for finals. Quality matters more than quantity — use active recall, practice problems, and spaced repetition rather than passive re-reading.
Does sleep affect exam performance?
Yes, significantly. Research shows that sleeping less than 6 hours the night before reduces cognitive performance by 15–25%. Memory consolidation happens during sleep. Students who sleep 7–8 hours typically outperform those who pull all-nighters, even with less total study time.
How do I improve my predicted score?
Focus on controllable factors: increase study hours (diminishing returns above 6h/day), ensure 7–8 hours of sleep, do a revision session within 24 hours of the exam, rate preparation honestly, and practice with past papers rather than just reading notes.
