For each Prelims section it combines your accuracy in that subject with how much of the syllabus you have covered, estimates how many questions you would attempt, and applies the 0.25 negative marking. It is a guide, not a prediction of your real result.
The projected score is an estimate out of 100, worked out separately for English (30), Numerical Ability (35) and Reasoning (35), then added.
The three ingredients
- Accuracy: the share of your answers in that subject that were correct, across practice and mocks.
- Coverage: how much of the subject you have practised, weighted by topic priority. High-priority topics count 3, medium 2, low 1. A topic counts as fully covered after about 15 answers.
- Estimated attempts: starts at 45% of the section's questions and rises towards 85% as your coverage grows.
The formula
Projected section score = estimated attempts × (accuracy − (1 − accuracy) × 0.25)
Example
| Step | Reasoning section (35 questions) |
|---|---|
| Coverage | 50% |
| Estimated attempts | 35 × (0.45 + 0.4 × 0.5) = 22.75 |
| Accuracy | 80% |
| Net per attempt | 0.80 − 0.20 × 0.25 = 0.75 |
| Projected | 22.75 × 0.75 ≈ 17 out of 35 |
How to raise it
- Cover more topics, starting with high-priority ones, to raise estimated attempts.
- Improve accuracy, which counts twice because wrong answers also subtract.
Limits
It does not know the difficulty of your real paper, your speed under exam pressure, or the cut-off in your state. A section shows 0 until you have answered questions in it. Treat the number as a progress meter, and check it against your full mock scores.
Why it can differ from your mock scores
The projection uses all your answers, including easy practice questions, so it can run ahead of your timed mock scores. Mock scores include time pressure and question selection. If the projection is much higher than your mock average, your speed, not your knowledge, is the gap.
