Weight governance
Weights must come from the current blueprint, not from perceived difficulty.
Education
Combine certification blueprint section scores with explicit weights and expose every contribution.
CERTIFICATION BLUEPRINT WEIGHTED SCORE
Enter four blueprint domain scores and their declared weights. The ledger keeps domain contribution visible so a strong total cannot hide a weak critical domain.
Decision boundary:For candidates and instructors prioritizing blueprint domains; it exposes contributions but does not reproduce an official scaled-score or domain-floor rule.
DECISION MAP
Use the weakest domain for targeted practice; do not let the weighted total erase a safety-critical domain requirement.

| Blueprint domain | Score (%) | Weight (%) | Contribution (points) | Interpretation |
|---|
LIVE CALCULATION PROCESS
R = sum(s_i x w_i / 100), with sum(w_i) = 100%
Each domain score stays on a 0-100 scale, its blueprint weight is converted once from percent to a decimal share, and all unrounded contributions are summed. The composite is a planning index, not an official scaled score.
| Symbol | Meaning | Unit | Current input |
|---|---|---|---|
| s1 | Core knowledge diagnostic score | % | 78 |
| w1 | Core knowledge blueprint weight | % | 25 |
| s2 | Applied questions diagnostic score | % | 84 |
| w2 | Applied questions blueprint weight | % | 30 |
| s3 | Timed practice diagnostic score | % | 69 |
| w3 | Timed practice blueprint weight | % | 20 |
| s4 | Review discipline diagnostic score | % | 88 |
| w4 | Review discipline blueprint weight | % | 25 |
HOW TO USE
SUBJECT FUNDAMENTALS
CALCULATION METHOD
Each domain score stays on a 0-100 scale, its blueprint weight is converted once from percent to a decimal share, and all unrounded contributions are summed. The composite is a planning index, not an official scaled score.
DEEPER ANALYSIS
Weights must come from the current blueprint, not from perceived difficulty.
A high composite can coexist with a failing domain-specific rule.
Recalculate after each comparable mock rather than mixing old and new scores.
WORKED DECISION CASES
Scores of 78, 84, 69, and 88 with weights of 25%, 30%, 20%, and 25% produce contributions of 19.5, 25.2, 13.8, and 22.0 points. The composite is 80.5%, while Timed practice remains the weakest raw domain at 69%.
Scores of 90, 60, 75, and 80 with weights of 40%, 20%, 25%, and 15% produce 78.75% overall. Applied questions is still only 60%, so a certifying-body domain floor can override the apparently comfortable composite.

FREQUENTLY ASKED QUESTIONS
The calculator rejects the record so the denominator is explicit.
Yes, which is why the ledger and weakest-domain card are both shown.
Only when their question sets and conditions are comparable.
No; scores are bounded to the declared scale.
No; pass rules may include domain floors or scaled scoring.

IMPORTANT NOTE
Use for study prioritization, not certification admission or pass/fail claims.
