Chemistry - Solid State

Practise 56 TS 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 TS EAMCET tests.

Solid State has been asked in 14 of the 24 years of TS EAMCET papers analysed (2001–2024), with 56 questions in all. 32% of them were easy, 57% moderate and 11% tough. Most of its questions came from 2020, with 8 questions that year. In the last three years (2022–2024) it had 17 questions across 17 papers, about 1 per paper.

The chapter's 6 topics are not weighted equally: Cubic system (38 questions, 68%), Crystal Structure of Solids (6 questions, 11%), and Stoichiometric defects (6 questions, 11%) have been asked the most. Cubic system has also led over the last five years, with 20 questions. Stoichiometric defects has produced the most tough questions (3).
