RPSC Assistant Electrical Inspector Marking Scheme

Important Instructions for OMR Sheet:

• Each question has five options (1, 2, 3, 4, 5).
• Candidates must darken only one circle using a blue ballpoint pen.
• For unattempted questions, darken circle '5'. Failure to do so will result in a 1/3 mark deduction.
• Candidates must ensure they darken one circle for at least 90% of the questions to avoid disqualification.

RPSC Assistant Electrical Inspector Time Duration

• Total Duration: 2 hours and 30 minutes (150 minutes)
• Extra Time: 10 minutes beyond the scheduled time for darkening circles on the OMR sheet.

Exam-Day Tips for RPSC Assistant Electrical Inspector

Before the Exam:

1. Document Preparation:

   • Carry the admit card (e-admission certificate) and a valid photo ID (Aadhar Card, PAN Card, Driving License, etc.).
   • Bring a blue ballpoint pen and a pencil for rough work.
   • Ensure your Aadhar card photo is updated if it is older than 3 years.

2. OMR Sheet Practice:

   • Familiarize yourself with OMR sheet filling to avoid mistakes during the exam.
   • Practice darkening circles neatly and accurately.

3. Syllabus Revision:

   • Focus on high-weightage topics such as Electrical Machines, Power Systems, and Control Systems.
   • Revise formulas, theorems, and diagrams thoroughly.

4. Mock Tests:

   • Take timed mock tests to improve speed and accuracy.
   • Analyze mistakes and work on weak areas.

On the Exam Day:

1. Time Management:

   • Allocate 1 minute per question and keep 30 minutes for revision.
   • Attempt easier questions first to secure marks quickly.

2. Negative Marking Strategy:

   • Avoid guesswork. Only answer questions you are confident about.
   • If unsure, darken circle '5' to avoid negative marking.

3. Stay Calm:

   • Read questions carefully and avoid silly mistakes.
   • Manage stress by taking deep breaths if needed.

4. Follow Instructions:

   • Listen to the invigilator’s instructions carefully.
   • Do not carry prohibited items like calculators, mobile phones, or study materials.

After the Exam:

1. Avoid Discussion:

   • Do not discuss answers with peers to avoid unnecessary stress.

2. Prepare for Document Verification:

   • Keep original documents (educational certificates, caste certificates, experience letters, etc.) ready for verification.
   • Ensure all documents are valid and up-to-date.

3. Check Official Updates:

   • Regularly visit the RPSC official website (rpsc.rajasthan.gov.in) for results and further notifications.
