Formula used

The calculator converts your preparation signals into a readiness value using a logistic model, then maps readiness to a predicted score and pass likelihood.

1) Readiness
z = b0 + Σ(wi · xi) + level_factor
readiness = 1 / (1 + e−z)
Inputs are normalized to 0–1, with diminishing returns for weeks and question volume using a log scale.
2) Predicted score and likelihood
predicted_score = 30 + 70 · readiness
pass_likelihood = 1 / (1 + e−(predicted_score − threshold)/5)
The threshold slider shifts the curve around your predicted score.

This is a heuristic estimator designed for planning. Real results depend on exam format, question pool, and day-of conditions.

How to use this calculator

  1. Set your threshold based on the exam’s published pass mark.
  2. Enter your latest mock and practice stats from timed sessions.
  3. Add labs and coverage to reflect hands-on skill depth.
  4. Include lifestyle factors like sleep, stress, and distractions.
  5. Review the drivers and tips to focus the next study week.
  6. Export CSV or PDF to track progress over time.

What the likelihood score represents

The calculator estimates a pass likelihood by converting preparation signals into a readiness value and then into a predicted score. Readiness is calculated with a logistic curve, so improvements matter most near the middle range. A predicted score of 70 against a 70 threshold yields about 50% likelihood, while 80 often exceeds 80% today.

Inputs that move the prediction

Timed mock performance and practice accuracy carry the strongest weight because they reflect exam conditions and error patterns. Study hours, lab time, and objective coverage add steady gains, but with capped impact to prevent unrealistic inflation. Question volume uses a logarithmic scale, so the jump from 100 to 300 questions counts more than 1600 to 1800. Revision sessions support recall speed, while sleep and stress shape consistency.

Handling difficulty and pass thresholds

Exam level applies a small difficulty factor to reflect deeper scenario questions and tighter pacing. Use Entry for fundamentals, Intermediate for mixed domains, Advanced for scenario heavy tests, and Expert for highly practical assessments. The pass threshold shifts the curve around your predicted score; a 5 point score gap changes likelihood sharply. If your certification publishes a scaled pass mark, enter the closest percentage equivalent and keep it consistent for tracking.

Tracking progress across study cycles

Run the calculator after each mock cycle, ideally once per week. If your likelihood is low, aim first to lift coverage toward 80 to 95% and move practice accuracy into the 75 to 85% band. When your score is moderate, add two timed mocks and review every wrong answer. At high likelihood, shift to endurance sessions, lab drills, and targeted weak objectives. Export CSV to compare predicted score, band, and key drivers.

Limitations and responsible use

This tool is a planning aid, not a guarantee. Real outcomes depend on question selection, stress on the day, and time management under pressure. The estimator uses simplified weights and cannot capture every domain nuance or lab environment. Treat the likelihood as a direction signal: increase sleep, reduce distractions, and retest with fresh mocks. If your predicted score stays under the threshold for three weeks, revise your plan or extend the timeline.

FAQs

How should I interpret the pass likelihood percentage?

Treat it as a planning estimate based on your inputs. Higher percentages indicate stronger readiness signals, especially mocks and accuracy. It is not a guarantee, so confirm progress with fresh timed practice.

Which input usually increases my likelihood the fastest?

Improving timed mock scores and reviewing mistakes typically moves the result fastest. Pair this with higher practice accuracy and better coverage of objectives to avoid weak-domain penalties.

Why does question volume show diminishing returns?

The calculator uses a logarithmic scale for practice questions. Early growth from low volume reflects rapid learning, while later gains are smaller because repeated exposure adds less new information.

What does the exam level setting change?

Level applies a small difficulty adjustment to reflect deeper scenarios and stricter pacing. Choose the level that matches your exam blueprint, not your confidence, for a more realistic estimate.

Can I use this for practical lab-based exams?

Yes, but enter realistic lab hours, coverage, and mock results that mimic hands-on tasks. For heavily practical tests, prioritize labs and timed simulations because memorization alone can overstate readiness.

How can I track improvement over time?

Run the calculator weekly, export CSV, and compare predicted score, band, and key drivers. Keep the same pass threshold, and update mocks, accuracy, and coverage after each study cycle for clean trend lines.
