The Chemistry syllabus for EAMCET 2026 (EAPCET) remains consistent with the Board of Intermediate Education (BIE) curriculum for Class 11 and Class 12. Chemistry is often considered the most scoring section because many questions are direct and memory-based.
Weightage & High-Yield Topics
| Category | Questions | Key Areas to Master |
|---|---|---|
| Organic Chemistry | 10 - 12 | Hydrocarbons, Carbonyl Compounds |
| Inorganic Chemistry | 10 - 12 | p-Block Elements, Chemical Bonding |
| Physical Chemistry | 12 - 14 | Solutions, Atomic Structure, Equilibrium |
