How ShiftRank calculates score and predicted rank

ShiftRank reads your official response-sheet page, applies the marking scheme, and compares your score against live submissions from the same exam to estimate rank.

From pasted URL to live estimate

This is the part users usually want explained in plain English: what gets extracted, how marks are applied, and why the public leaderboard can differ slightly from what a user typed in.

1. Extracting responses from the official page

When you paste the official URL, ShiftRank fetches that response-sheet page and reads the questions, your chosen answers, and the officially correct responses. When available, it also captures useful exam details like shift, subject, or session.

2. Applying the marking scheme

Positive score

Correct answers × marks per correct answer

Negative score

Wrong answers × negative deduction

Raw Score = Positive Score − Negative Score

3. Estimating public leaderboard position

Rank prediction is based on live submissions already stored for the same exam identifier. ShiftRank compares your score against that pool and estimates where you stand overall and, where enough data exists, within relevant segments.

4. Why the public board uses a fairer score

Some users choose the wrong scoring scheme or intentionally inflate it. To keep public ranking fair, ShiftRank normalizes the public leaderboard using the consensus scheme most users of that exam are following.
