The exam is built around a technical trade syllabus, but the notification also allows for questions from other topics tied to the SSLC-level educational qualification \u2014 so a complete book list needs to cover both the core trade content and general-studies backup. This guide lists every category of book worth using, why each one matters, and how to prioritise between them.
