Chemistry - Solid State

Practise 87 AP EAMCET previous year questions on Solid State, compiled from papers spanning 2008 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty AP EAMCET tests.

Solid State has been asked in 13 of the 24 years of AP EAMCET papers analysed (2001–2024), with 87 questions in all. 46% of them were easy, 48% moderate and 6% tough. Most of its questions came from 2022, with 19 questions that year. In the last three years (2022–2024) it had 36 questions across 28 papers, about 1.3 per paper.

The chapter's 7 topics are not weighted equally: Cubic system (57 questions, 66%), Stoichiometric defects (7 questions, 8%), and Crystal Structure of Solids (6 questions, 7%) have been asked the most. Cubic system has also led over the last five years, with 35 questions. Cubic system has produced the most tough questions (5).
