The 28 January morning shift was moderate-to-hard, with Mathematics being the major time sink, Chemistry moderately tricky (organic-heavy), and Physics relatively scoring but still concept-driven.
| Subject / Overall | Difficulty Level | Lengthiness | Time Consumption | Question Nature | Key Observations |
|---|---|---|---|---|---|
| Physics | Easy to Moderate | Short to Moderate | ~60 minutes | Formula + Concept based | Easiest among three but comparatively harder than Physics of other shifts; balanced and scoring |
| Moderate to Difficult | Lengthy | ~70–80 minutes | Calculation intensive + Conceptual | Toughest section; very time-consuming; required strong accuracy and selection strategy | |
| Chemistry | Moderate | Moderate to Lengthy (Organic heavy) | ~55–60 minutes | Statement-based + Named reactions | Organic dominated; Physical had statement-type questions; doable with solid revision |
| Overall Paper | Moderate to Hard | Lengthy overall | Time management critical | Statement-based trend continued | Maths > Chemistry > Physics in difficulty; tougher than many previous shifts |
