Since the Central Board of Secondary Education (CBSE) released Class 12 results on May 13, social media platforms have been flooded with concerns about the evaluation process conducted through On-Screen Marking (OSM). Anxious students have claimed that poor scan quality might have led to errors in marking, among other reasons. The discontent among students was particularly strong in subjects such as Mathematics, Physics, and Chemistry, where many felt their answers were undervalued. Some also pointed to discrepancies, noting that candidates who scored 95 percentile or above in JEE Main ended up with unexpectedly lower marks in the CBSE board exams.
Responding to the criticism, CBSE, in a media brief held on May 17, acknowledged a minor dip in both pass percentage and average marks this year. Sanjay Kumar, Secretary, Department of School Education and Literacy, Ministry of Education, explained that the cut-offs in subjects such as Physics, Chemistry, Mathematics, and Accountancy had dropped by 1–3 marks, while other subjects remained stable or even rose.

The board attributed this shift to evaluators following the marking scheme prepared by subject experts, which emphasises rigour and conceptual understanding over shortcuts. CBSE maintained that the system ensures fairness and consistency, while also offering students the option of revaluation and verification to address grievances.

The data table shared by CBSE shows that in Mathematics, the A1 grade now begins at 85 marks, down from 86 in 2025 and 88 in 2024. Physics shows a sharper slide, with the A1 threshold falling to 79 marks from 82 in 2025 and 84 in 2024. Chemistry too reflects a decline, with the A1 cut-off at 87 marks, compared to 89 last year and 92 in 2024. Biology remained stable, with the A1 grade holding at 91 marks, unchanged from 2025.
On the other hand, in the Commerce stream, there isa minor dip in cut-offs across commerce subjects in 2026 compared to previous years. In Economics, the A1 grade now begins at 89 marks, down from 91 in 2025, while A2 has slipped to 81–88 from 83–90.
