How to Prepare for the WBPSC IDO Exam

Time Allocation Strategy

1. Start with high-weightage sections: Mental Ability and Arithmetic (20 marks) first, then English, Environment, Physical Science and Industrial Scenario (15 marks each).
2. Master the West Bengal angle: Industrial potential and state schemes are rarely covered in generic GK books, so they give you an edge.
3. Revise science basics: Class 9 to 12 level Physics and Chemistry is sufficient.
4. Take mock tests: Practise in the real format of 100 questions in 90 minutes. Try our Mock Tests and Daily Quiz.
5. Manage negative marking: Each wrong answer costs 0.25. Attempt questions you can eliminate down to two options and skip pure guesses.
6. Prepare for the interview: Revise your educational subject, basic MSME knowledge and speak Bengali confidently.

Sample Scoring Math

If you attempt 90 questions and 80 are correct, you score 80 - (10 x 0.25) = 77.5 marks. That is why accuracy matters more than the attempt count.

PwBD Scribe and Compensatory Time

Eligible PwBD candidates with limitation in writing may use a scribe and get 20 minutes compensatory time per hour on production of a valid Appendix-I certificate. Engagement of a scribe cannot be accepted after final submission of the application.

• Madhyamik or equivalent certificate with photograph
• Passport
• PAN card
• EPIC (Voter ID)
• Driving licence
• Any other ID issued by State or Central Govt.

Exam Day Rules to Remember

• A valid admit card is mandatory; the venue cannot be changed
• Mobile phones, Bluetooth devices and smart watches are strictly prohibited; frisking is done at entry
• Applying more than once leads to cancellation of candidature
• Application once submitted is final; false information leads to penal action
