What this book is for in TNPSC
Science feeds the General Science unit. The syllabus allots it a small share of General Studies, but past papers ask far more from it than that, and the questions come straight from these chapters: physics, chemistry, biology and the human body at school level. Classes 6 to 10 are SSLC standard, which is the standard the Group 4 and Group 2 General Studies syllabus is set at.
Read the chapter, then answer the questions TNPSC actually asked from it: every paper from 2023 on can be practised free on this site, question by question.
