Pattern observations:
- Radioactivity and fuels — asked nearly every exam; high probability for 2026.
- Green chemistry and green hydrogen — not asked in old pattern; highly probable given 2026 syllabus explicit inclusion.
- Drugs — antibiotics, antiseptics classification questions expected.
- Alloys — minor but regular 2-mark Q source.
