How to use the OMR Sheet Practice
- Pick a pattern (SSC Tier-I, GD, MTS Session-II, UPSC GS or CSAT) or set your own questions, marks and time.
- Press Start and mark one bubble per question. Tap a filled bubble again to clear it.
- Submit, then enter the answer key by tapping or by pasting letters such as ABCD.
- See your score and a colour-coded sheet. Use Print blank OMR sheet to practise on paper.
Marking used by the presets
| Preset | Questions | Correct | Wrong |
|---|---|---|---|
| SSC CGL/CHSL Tier-I | 100 | +2 | −0.50 |
| SSC GD Constable | 80 | +2 | −0.25 |
| SSC MTS Session-II | 50 | +3 | −1 |
| UPSC Prelims GS Paper I | 100 | +2 | −2/3 (about 0.67) |
| UPSC CSAT | 80 | +2.5 | −5/6 (about 0.83) |
UPSC deducts one-third of the marks of a question for each wrong answer. Example: in a 100-question GS paper, 60 right and 24 wrong gives 120 − 24 × 2/3 = 120 − 16 = 104. A question with no key letter is treated as dropped and left out of the total.
Limitations
- This is a practice sheet for printed or on-screen mock tests; it does not include questions.
- Real OMR sheets are read by a scanner, so in the exam a half-filled or double-marked bubble can be rejected. Here a tap fills the bubble completely.
- Your sheet is saved in this browser until you start a new one.

Frequently asked questions
How do I practise filling an OMR sheet?
