Formula Used
Raw Score = Correct Answers × Marks Per Question - Wrong Answers × Negative Marking + Bonus Marks + Objection Marks
Normalization Delta = Overall Average Gap × 0.55 + Top Score Gap × 0.15 + Difficulty Adjustment
Normalized Score = Raw Score + Normalization Delta
Percentile = Score Percentage + Difficulty Boost - Competition Penalty
Predicted Rank = ((100 - Percentile) / 100) × Appeared Candidates + 1
Selection Chance = Score Gap + Percentile Strength + Vacancy Position + DV/Skill Factors
This formula is predictive. Replace demo weights with your own historical score distribution when real data becomes available.
How To Use This Calculator
- Select the HPRCA exam year, post name, exam type, shift, and answer-key stage.
- Choose your category, domicile status, district, qualification status, and document readiness.
- Enter correct, wrong, skipped, bonus, deleted, and accepted-objection question counts.
- Use manual score only when you already know the official score.
- Enable section-wise scoring if you want the tool to calculate score from subject sections.
- Paste answer-key tokens and response tokens for a quick question-wise analyzer.
- Enter vacancies, category seats, appeared candidates, and submitted data count.
- Submit the form and review rank, cutoff, percentile, DV chance, waiting list chance, and final merit probability.
Admin Configuration Guide
This page is a single-file calculator. The top PHP section contains the arrays named $examCatalog, $postCatalog, $categoryList, and $sectionTemplates. A site owner can edit these arrays to add new exams, post codes, official vacancies, revised vacancies, cutoff records, and section names.
Insert a new key in $examCatalog with questions, marks, mode, and scoring pattern.
Insert a new key in $postCatalog with name, department, vacancies, and cutoffs.
Replace sample category cutoffs after official or reliable historical data is available.
Add a database only after adding privacy consent and secure data deletion options.

Understanding HPRCA Rank Prediction
Why rank prediction needs many inputs
A recruitment rank cannot be predicted from marks alone. A score becomes useful only when it is compared with total vacancies, category seats, paper difficulty, number of candidates, previous cutoff behavior, and the size of the available response data sample. This calculator keeps those inputs visible. That makes the output easier to audit.
Why category rank matters
Many candidates focus only on overall rank. For recruitment selection, category rank may be more useful. A candidate with an average overall rank can still be competitive inside a smaller category pool. The tool estimates category rank by applying a configurable category share to the appeared candidate count. For a production website, this value should be replaced with real category-wise participation data.
Why cutoff is shown as a range
Cutoffs move when vacancies change, objections are accepted, difficult shifts receive score adjustments, or many high-scoring candidates appear in one category. Because of this, a single exact cutoff can mislead users. The calculator shows a low and high cutoff range around the predicted cutoff. This makes the result more practical for borderline candidates.
Why normalization is optional
Some exams may use a single shift. Some may use multiple shifts. Multi-shift exams may need normalization because one paper can be harder than another. This calculator includes shift average, overall average, top score, and difficulty index. Users can turn normalization off when the exam does not require it.
Why the result is unofficial
Official selection depends on the recruiting authority, final answer key, reservation rules, document verification, skill test results, tie-breaker rules, and the official merit list. This calculator only provides an estimate. It helps candidates understand their position, but it should not be treated as a final result.
