The Laboratory Technician (Chemistry Group) Class-3 examination carried 210 objective questions split across two parts. The board has cancelled 1 question in Part - B and changed answers on others. Because Part - A retains all 60 questions, its marking remains unchanged; Part - B applies a pro-rata weight since one question has been cancelled.
Part | Live Questions | Total Marks | Correct Answer | Wrong Answer |
|---|---|---|---|---|
Part - A | 60 (no cancellation) | 60 | +1.0 mark | -0.25 mark |
Part - B | 149 (out of 150; 1 cancelled) | 150 | +1.00671 marks | -0.25168 mark |
The Part - B per-question weight rises above +1.0 because the cancelled question's mark is redistributed pro-rata across the remaining 149 live questions while the total of 150 marks is preserved.
