Is there negative marking in OPSC OAS?
No. OPSC OAS has no negative marking, so attempt every question — an unanswered question scores the same as a wrong one (0). Accuracy still matters for cutoffs, but never leave blanks.
How should I cover the OPSC OAS syllabus?
Work section by section: master one subject at a time with topic-wise practice, then combine sections in full-length mock tests under the real 120-minute timer. Analytics from each mock show which syllabus areas leak marks, so your revision targets weak topics instead of re-reading everything.
